  1. Hello everyone, On my 2020 GMC Sierra 2500HD Denali I did a hood air induction vent swap for a chrome vent cover and while I was at it I added Led RGB lights inside the vent taking care not to restrict the air flow. Has anyone else done any chrome or Led RGB mods? If so lets see them please.
  2. Thom Cannel: Article & Photos Zane Merva: Photos & Video GM-Trucks.com June 25th, 2019 By now you prospective 2020 Chevrolet Heavy Duty owners are over the Ho-Hum of our 2020 Silverado 3.0-liter story (we are totally Ho-Ho-Ho and Hmmm, can’t wait for a longer test!) and looking at the Alpha Dog, the 35,500-pound tow-rated Silverado Heavy Duty and its over 50 industry firsts including an updated diesel engine and all-new 6.6-liter gas engine. Let’s get to it. Where to start? With its amazing trailer towing features that include 15-view camera and ability to memorize the features of five different trailers? How about the Durabed with its class-leading cargo volume and all-steel construction with a plethora of cargo tie-downs? Maybe you’re gobsmacked by the corner and bed steps with, now, plenty of toe room and 500-pound weigh-holding capacity? Is it the power tailgate that remotely lifts or lowers? An ability to hold first gear while towing maximum weight? Or, is it all of these? Chevrolet states that Heavy Duty trucks are working vehicles, whether towing a gooseneck horse trailer or flatbed and whether gas or diesel-powered. They further tell us that, compared to light duty trucks where 84-percent are retail and 12-percent go to fleets, Heavy Duty buyers are 70-percent retail and 30-percent fleet. Further, Work Truck and Custom trucks make up the volume; LTZ and High Country capture an even larger share of the market for personal and dual use buyers, with mid-trim LT trucks straddling fleet and personal use. Hence the five available trim levels to suit the needs of every buyer. There is no mistaking that the 2500HD and 3500HD is kin to the 1500, yet only roof sheet metal is common. Everything about the new HD trucks was designed to be functional from larger grille to lower side-height bed, to improved box and bed steps. It’s massively bold with strong character lines, huge fender wells and functional hood scoop. Both the 2500HD and 3500HD are distinctive and clearly Chevrolet. For 2020, every frame is boxed and steel, there’s a model with built-in gooseneck cross-body reinforcements and bed holes, 4X4 models can option Autotrac two-speed electronic transfer case, the DEF tank is relocated inside the frame rails with the filler under the fuel door, plus a 10-segment DEF gauge measures content. A statistic to toss off at your microbrewery; within the total HD segment, 54-percent are Crew Cab diesels while within fleets, 62-percent are gas-powered, with 34-percent of fleets buying Crew Cabs and diesel power. And if you’re wondering where the 2020 Silverado HD you’d like to scope out on your dealer’s lot is hiding, Crew Cabs began delivery last week with Regular Cab, Double Cab and Duallies hitting the streets this fall. Restrain yourselves. Let’s now talk about the biggest reasons for owning a Heavy Duty Chevrolet (or GMC). It’s towing. And if you’ve noticed comments to our 15-camera article, there’s some passion about technology. Realistically, as many HD trucks are sold to new truck owners towing large RVs, anything that improves road safety is flat wonderful. If you further read Chevy’s research that says 12-percent of pickup drivers have gotten into a fight with their significant other over trailer hookup, you’ll understand executive chief engineer Tim Herrick’s comment that “We save marriages.” Having driven every truck segment from light duty to tractor-trailers we feel you. So, when research says a majority of drivers are stressed by towing, please offer them a 2020 Silverado sales brochure and a tissue (and save a tissue for yourselves ‘cause you might be exaggerating your tow-cool). So let’s dive deeper into the subject. Everyone has a hitch camera these days, with overlaid guidelines to put you within a few inches, front-to-back, of the ball. Chevy goes further with a selectable view that looks own over the ball. Even those who haven’t set a hitch in years—or never—can get within a quarter-inch of perfect. And an APB or automatic parking brake engages automatically so that when you lift off the brake pedal you don’t roll off the ball. Sticking with the non-pros and semi-pro haulers, there’s a checklist for your trailer, the ability to check the lights after connecting the trailer’s electrical system, a tow-haul reminder and VIN-specific labels for the trailer itself. If you option the smart trailer integration, which is designed to work with ASA Electronics iN∙Command® control system, you have control over trailer features like heat and air conditioning through the infotainment system or the myChevrolet mobile app. And nobody should turn down the ability to monitor trailer tire pressure and temperature. Blowouts are never convenient and most often low-pressure and highly temperature related, according to Michelin Tire Company. We found the 15-view system difficult to get used to during the first five minutes, particularly when backing; our mirror habits are embedded. Yet, simulating tight turns where we could see along both the tight and far side, pulling forward into a tight box, or backing (after a few tries), we really came to appreciate what the system could do. Then, on the highway with an 18,000-pound box trailer behind us, mirrors just didn’t cut it compared to the high-tech camera system. We were driving on twisting two-lane blacktop in mountain foothills. Using the entire camera tech set, particularly the ability to look out the back of the trailer, we could easily pick places to pull aside to let faster cars pass us. It took less than an hour to become a must-have feature. Later we towed a smaller skid-steer on a flatbed without the system and truly missed it despite using our slide-out mirrors fully extended. This naturally leads to the two engines offered in the 2020 Heavy Duty, first the 6.6-liter V-8 purpose-built gas engine that delivers 22-percent more torque than its predecessor. Now it delivers 401 horsepower and 464 lb-ft of torque. It’s mated to a six-speed automatic transmission. The 6.6L isn’t a just a 6-mm stroked 6.0L, rather it takes advantage of the Gen5 small block architecture and has a unique cast iron block with forged powdered-metal connecting rods and forged crankshaft. The most significant change is the addition of Direct Injection. It’s all new, an industry first for the heavy-duty market and new to GM trucks. Direct Injection allows a compression ratio of 10.8:1 Quoting Mike Kociba, a GM engineer and part of the Small Block team, “Our suite of changes allows us to hit class-leading gasoline engine torque, at 464 foot-pounds at a lower engine speed than the outgoing six-liter was optimized for. I'm proud of its 401 horsepower, which is SAE Certified; no games, it’s legitimate. Customers can have confidence they're going to tow whatever trailer they need.” Don’t forget the larger cooling fan and newly designed water pump. The pump drives the fan through a one-inch shaft with unique bearing design to handle greatly increased thrust loads. Plus, the oil pump is now has variable output, so there’s less parasitic losses. The 6.6L engine features an aluminum oil pan, nylon 6-6 air intake, and stainless steel exhaust manifolds unique for the Heavy Duty market. Like related light duty Gen 5 motors, this motor has variable dual-equal valve actuation, massive Gen5 valves and uses an actuator that’s mounted to the front cover to control intake and exhaust valves. The new block features inter-bore cooling, that is, coolant flows through Siamesed bores, notably in the upper bores where there’s a tendency to generate higher temperatures. “Small engines with turbochargers allow them peak torque off idle,” Mike told us, “but for heavy duty we don't want that complexity. For the Heavy Duty segment we (General Motors) have durability requirements—Global Engine Durability—that are unique stringent. We know our customers and why we focus on durability. If they can't use their truck today, they might not get paid.” When towing a heavy load, we loved the diesel’s engine braking capability. What about the gas engine? In Tow-Haul, up-speeds caused by downhill driving—together with intelligence based on throttle position—the powertrain produced seamless downshifts. It’s not quite the same as engine braking, but the trailer was “only” 12,000 pounds. Regardless, it was a comforting addition to stress-free towing. The six-speed transmission used for 2020 Heavy Duty GM trucks is an updated 6L90 with an uprated torque converter and clutch pack. According to GM engineer Rich Mardeusz those changes were simple. When it came to the torque converter, things changed. “We looked at the components from a heavy-duty diesel torque converter and a high-output gas torque converter and then took the torque-carrying components from the diesel and married them to the spring and damping components from the gasoline torque converter. That’s what was needed to accommodate the approximate 22 percent across-the-board torque increase.” Those changes also damp out firing frequencies from the gasoline V-8 engine, making the powertrain smoother. Since a majority of buyers opt for the diesel engine, let’s look at that. Also displacing 6.6-liters, the Duramax turbo-diesel makes 445 horsepower and 910 lb-ft of torque. It’s coupled to a 10-speed Allison transmission. There were minimal changes to the engine for 2020. They include a 28-inch fan for cooling; upgraded oil cooler—now 19 plates instead of 14 and the cylinder head gasket was improved. Engine brake capacity is greater by 14-percent and while there’s a button for manual activation, while in Tow-Haul mode engine braking is automatically activated at certain RPMs. It’s Chevrolet keeping you safe. Thus, under the new control system the powertrain will recognize any need for the engine brake and activate automatically. For instance in driving down hill and forgetting to shift, the higher RPM means automatic activation. We did experience this with the18,000 pound box trailer and it is amazingly transparent and surprisingly quiet. You don’t have to downshift on modest hills, as the system will totally keep you at, or near your desired speed. Of course you may have to use a bit of smooth brake application if the grade is longer, or steeper. For really steep downhilling Plus-Minus buttons on the column-mounted shifter initiate gear changes. We’re not huge fans of the buttons as the steering wheel obscures their location and make it a bit fumbly to slide your thumb into position. A really important feature for 2020, diesel models add an engine after-run feature. Should you tow up a grade and park for dinner without a cool-down, the truck will do it for you. Run time is limited by temperature and shutdown is equally automatic. Because of the Allison/GM 10-speed transmission used for 2020, the powertrain required a complete recalibration. There are several positive results, according to David Ames, GM assistant chief engineer and Allison liaison. “Emissions have been improved and fine-tuned to maintain the best efficiency the transmission can offer to our customers.” It also has a fully warranted chain-driven engine-speed PTO available from the factory. The new 10-speed’s torque converter has a lock-up clutch that is unique as it will lock up in first gear, even under max loads. So, if you're pulling 35,500 pounds, you can do a first gear launch and lock up right away, which helps get rid of heat. We asked David why this is important. “Normally in first gear you're under high torque and generating a lot of heat, which puts a lot of demand on the cooling system. Locking up gets rid of that heat. Also, the new transmission has a lower 4.5:1 first gear with four planetary gear sets and six clutches. We noticed the low gear and ten speeds on launches and while pulling the box trailer on the highway. Often in hilly driving you're downshifting to save brakes; with ten gears we held the right speed and best RPM, particularly with automatic engine braking. We did drive a Silverado 3500HD dually at max capacity; 35,500 pounds on a closed course: our US Army CDL permit has lapsed. The claim of off-the-line torque is spot on. What was most interesting was the 3500’s ability to resist being pushed about on turns and we did several random serpentine loops to see if we could find any significant push? Nope. Later, with “only” 17,000 pounds behind us we finally found a bit of trailer push, which required a deeply rutted dirt road and an off camber turn. Nothing the truck couldn’t handle, even with a journalist behind the wheel. Many of us wondered why the different transmissions for Heavy Duty trucks, why not just the Allison ten? We asked and, while suspecting that plant capacity utilization and raw costs have something to do with it, were told by Vincenzo Verino, the 3.0L Duramax global chief engineer “It’s really about what the transmission brings to the engine itself. With a wider torque band, the gas engine is well-matched to a six-speed, while the narrower torque band of the Duramax is better suited to a 10-speed.” In the battle for Heavy Duty supremacy, big numbers are thrown around to convince potential buyers of worth and value. We found these slides from Chevrolet’s presentation compelling, showing Chevrolet doesn’t always have the biggest power numbers, yet can deliver more real world competency than competitors. Faster to 60 with better towing capability, we’ll take that over a bigger number any day. And Chevrolet says every diesel dually will tow more than 30,000 pounds the 2500HD with 6.6L gas engine has a tow capacity of 17,400 pounds, up 18-percent, that’s good regardless altitude. There is much, much more to tell in future stories, like the no-cut removable fascia for winter snow plow installation and the covered fender-mounted engine heater outlet, use reports of the up-down power tailgate and the bed’s 12 fixed and 9 moveable tie-downs. There’s details on improved axles, locking rear differential, beefed-up prop shaft and 12-inch ring gear, stronger U-joints, class-exclusive SLA front suspension (“mandating a solid front axle for HD trucks isn’t a thing” according to the chief engineer Tim Herrick) and the list goes on. We expect to write several more stories about the new trucks, each specific to how you’d use the truck and with even more details. We have only scratched the surface.
  3. Currently have my 2020 Gmc sierra 1500 with a build date of 09/2019 at the dealer with 2kmiles on it. Battery was dead one morning. After jump starting had check engine light and brake antilock system issue sent to my email. Truck would not hold a charge after leaving it on for a good 30 min. Its been at the dealer for 3days now.
  4. I'm about to install the Chevy Performance Brembo Brake Upgrade on our Silverado. Has anyone else installed this kit? Anyone thinking about it? At first glance, it seems pretty straightforward. After reading the manual, however, I'm realizing I need to take the front wheel bearings off to access the dust shield. Other than that, it seems to be a easy rotor/caliper replacement. Big thanks to @RyanbabZ71 for recommending a great brake bleeding tool! The front set is a true six-piston caliper. The rear calipers are stock calipers painted red to match the fronts. The size increase on the front rotors is significant. I'm gathering the tools I'll need right now. Hopefully I can tear into it next week. I expect the entire process to take me at least a whole day and maybe two days depending on how it goes. Why so long? I'll be photographing and taking video of the entire process. Can't wait to share that with you all. Check back in this thread for progress updates.
  5. Hello im new to this forum. I have been searching for silimar sounds my truck is making on here but i can't seem to find one. So my truck is a 2020 silverado rst 5.3 8 speed crewcab 4x4 and has 1,600 miles. It makes this clicking sound similar to a clock. I went underneath the truck to listen for the sound and it appears to be coming from transmission area. Any thoughts of what the sound is? Ill attach a sound clip. Its a cold start but it also does it when its warmed up. 20201103_053649_2_1.mp4
  6. Just installed the Go Rhino RB20’s with the Bed liner coating. I’m really happy with how they look... I wanted something high and tight to the bottom of the cab. 
  7. My new truck has cameras all over it. Front, side, rear, top. I figured out how to remove the tailgate, even made a short UTube video to help others, but after removing it, I found out that the camera system does not work. I still wanted the front, side, and top cameras to work with the tailgate off. Has anybody else encountered this? Figured out how to keep them working with the tailgate off?
  8. Iv been searching the Internet and have found multiple videos of how to install the 2 inch leveling kit but no one seems to do a comparison photo of before and after. I have a 2020 GMC sierra elevation blacked out with the stock rims and tires. Just trying to see if anyone has some pictures of before and after and which route is better for the leveling kit.
  9. Thought oil pressure was low so when I got home I checked the level, level was fine. However, the oil was black. Dealer did the first oil change maybe 1500 miles ago (only 8900mi on it currently) and the oil is black already. Is that normal? I understand that the black color indicates the presence of carbon and is normal, and does not mean it needs to be changed simply based on color. It didn't smell burnt or "old" either. I really do not run this truck that hard and especially not so during the last 1500 miles. I'm just hoping someone can educate me on the world of diesel engine oil and differences vs gas engine oil. I would expect the oil not to be thorougly black after such a recent oil change.
  10. I need to add a second battery to my 2020 Silverado CC. In previous years, it was simple. There was even a place. I don't see a single option or place to fit one. I called my local dealer multiple times to ask, but they never call back. Anyone else figured out a way to do this? Where is a good spot?
  11. New to this forum , but just wondering if 2019-2021 snowflake 22 wheels will fit a 2018 silverado.
  12. Has anyone added reverse lights on 2019-2021 sierra? I need ideas!!! I was thinking about rigid ignite flush mount. Show me what you did!!! thanks!
  13. Here is a video clip of a cold start the day after I added a Flowmaster Super 10 to my 2020 5.3 Silverado. All I had done was a muffler swap. Original pipe with mesh resonators is still in place. Sounds great and aggressive when accelerating and starting up but not too crazy when cruising. Haven't taken a long highway trip yet so not sure about drone on a long trip but I have been on short highway trips and the drone is very, very minimal, can't even hear it when music is playing.
  14. New 2020 Silverado 2500 diesel, newly retired, bought truck to tow a travel trailer. I've been a GM customer and amateur mechanic for over 50 years. I had not driven a 3/4 ton truck for decades, when I test drove a new 2500 I simply was stunned by the ride quality, to say the mechanical engineers have made improvements would be a world class understatement. The power, ride quality and tow features (mirrors and cameras) sold me within weeks of shopping. The size is a little off-putting but after only 8 weeks I have compensated for parking and maneuvering a very large pickup. The truck draws some jokes about its size but I absolutely love the towing performance, it is a worthwhile trade-off for me.
  15. After upgrading my base cluster and steering wheel. Is it possible to control the cluster from the new steering wheel? How is this wired? Ive seen videos for models up 2014-2018. However, nothing on new gen trucks (2019-2020).
  16. After upgrading my base cluster and steering wheel. Is it possible to control the cluster from the new steering wheel? How is this wired? Ive seen videos for models up 2014-2018. However, nothing on new gen trucks (2019-2020).
  17. I own a 2019 next gen sierra (elevation) and I'd like to install the extended view tow mirrors (part # 84776098). My truck is equipped with DLF and not UKC as specified in the part description. GM says these mirrors will not work on my truck …. GM enthusiasts. Is this true? I feel like it's bullshit and the harnesses are plug and play? If they're not plug and play, is there an alternate harness? It can't be possible that this 1/2yr model can't be equipped with tow mirrors? Help please …..
  18. Zane Merva Executive Editor / Publisher - GM-Trucks.com June 21st, 2019 We recently had a chance to check out the all new Silverado HD. The 2020 Silverado HD has an optional 8 camera system to help aid in towing your trailer. We get a full walk through of the various views and camera angles.
  19. Hello, I just recently got some additional lights to put on my offroad bumper, and don't know where exactly to put the switch or how to integrate it into my dash. I just need to be able to add two sitches. I was thinking of trying to put them near the parking brake, or on the instrument panel. The instrument panel already has two spots not being used but they don't press down. Any tips or ideas would be greatly appreciated. Thank you.
  20. So I recently purchased a 2020 GMC Sierra and I have the jump seat configuration Id like to switch to the jump seat to a center console and I was wondering has anyone done that on a 2019 or a 2020 GM truck already? I feel this is a do-able modification to my vehicle but Im looking to see what I would need to do. If anyone could point me in the right direction that would be greatly appreciated.
  21. Has there been any recent updates this year? I have a 2020 LT Trail Boss and I was wondering about how big of wheels, tires you can put on without lifting it more than the 2 inch that it already has? Also has anyone changed their LED bulbs, I was considering changing mine to brighter ones mine seem not so bright.
  22. Long time no see, today for my first oil change I brought up the fact that my truck sometimes shifts hard coming to a stop. Always the 2-1 shift. This was the response... the service advisor said “there is a lawsuit in the states”.. dunno if that’s true? Looking for opinions, will this ever go away?!
  23. TL;DR: I drove 2,941 miles from South Florida to Southern California in my brand new Sierra 1500 AT4 Duramax and pulled my 4,400lbs pound boat. I experienced no drivetrain issues other than running out of gas which was my own fault. I kep the rpms mostly at 1500-2100, averaged 12.6 mpg, consumed 11-12 gallons of DEF and had no cooling issues under the load and in the 118F heat of the Californian desert for the prolonged time I was driving. The trailering app and trailer tire TPMS system paid for itself and was a great tool for safety! DEF gauge may not be accurate to read when towing, rather go by the mileage warnings that display on the dash. Adaptive cruise control disengaged briefly but was able to re engage after turning the truck off and back on again. I am very satisfied with the performance I experienced and overall truck and have had no issues thus far with the drivetrain (6,054 miles on the clock). Hey y'all, I wanted to put some info out there about the trip I just made this week from Boca Raton, FL to San Diego, CA in my brand new 1500 AT4 Diesel to include performance numbers, issues I encountered, good, bad, and otherwise. I was a little on edge seeing as I did a decent amount of research on the new duramax before I bought it in July and there are definitely some issues out there that are yet to be addressed, however I had to move for my new job so here goes. Google Maps put the trip at 2,611 miles (4,202km) from my parents driveway to my new place but my trip clock read 2,941 miles (4,733km) due to stopping in to see some family along the way. I had 3,110 miles (4,989km) on the clock before I left. Note that my backseat was full of boxes and my bed was mostly empty except a weatherproof toolbox because I don't have a tonneau cover yet and did not want my items exposed to the elements or sticky fingers for the five days I was on the road. I was also towing my boat which is a 20 foot center console on a tandem axle trailer with dual axle hydraulic surge brakes. The boat and trailer combo weighs 4,400lbs (1995 kg) as indicated by the weigh scale I stopped at in California and my WeighSafe drop hitch with tongue scale. I spent the overwhelming majority of my time at ~1500 rpm while on cruise control at 67-mph but would jump to ~2100 when gradually accelerating. I left on Sunday afternoon and drove 225 miles (362km) to Daytona Beach, FL mostly uneventful despite my DEF warning popping up saying I had a 1000 mile range. On Monday, I drove 514 miles (827km) uneventfully seeing some family and friends in the Panhandle of Florida. The only eventful part of this leg of the journey was the DEF message popping up in the morning saying I had a 300 mile range approximately 150 miles after the 1000 mile warning and a speed limited soon message shortly after the 300 mile message. I figured I would use more DEF while towing but I hadn't put much thought into exactly how much I would use while planning my trip. I will talk more about DEF later. Tuesday I drove 537 miles (864km) from Milton, FL to Houston, TX uneventfully. Somewhere around San Antonio, TX I got a message that adaptive cruise control has disengaged. I was able to switch to regular cruise control but still don't know why that happened. I was able to re engage adaptive cruise control later in the day after I turned off the truck at a fuel station. Any thoughts would be appreciated here if you have experienced something similar. Wednesday is where the fun started. About halfway between Houston and Fort Stockton (508 miles, 817km) I got a low trailer tire pressure message on my dash. My truck came with 4 trailer tpms sensors I had installed into 4 new tires on the trailer about a week before I left because I figured why not. the tires are filled to 50psi as per the sticker on the trailer and the message showed front right had 35 psi. I figured all was fine and it was an error message as I had already driven over 1000 miles with no issues but I decided to stop and check at the next exit as I noticed the pressure was steadily declining. I pulled off at a Love's and went to check and could hear the air coming out but couldn't see a nail or feel the air. Regardless (after re parking in the shade at 102F outside), I took the tire off and lo and behold found a 3 inch nail in the tread near the edge of the tire. Within 15 minutes I had it plugged, refilled, reinstalled, and ready to go. That right there ladies and gentlemen justified the $85 I paid to install the sensors. Had I not known of the diminishing air pressure I surely would've had a blowout at the most inconvenient location and had to put a spare on in the heat. So that sold me on the trailer tire TPMS system, cost to install already paid for itself by saving me from having to buy a replacement tire. On Thursday, the plan was to go from Fort Stockton, TX to Tucson, AZ (558 miles, 898km). I was about 30 miles away from my next planned fuel stop when my fuel level low light came on but I didn't think anything of it as I would be stopping about 20 miles before I ran out of fuel. When I pulled off at the only fuel station in the area (Akela, NM) which GasBuddy showed had diesel, I discovered much to my dismay that the station did not have a diesel pump. I knew I was probably screwed but didn't really have a choice but to shoot for Deming, NM which was 24 miles down the road. My fuel level read low so I reduced speed to improve economy and hoped for the best. Worst case scenario I run out of fuel much closer to an actual city which would reduce the time it took for a fuel delivery service to reach me. 5 miles out of Akela, a car flags me down and says something blew off my boat so I pulled over and saw that my bimini top had blown off. I figured my best course of action was to drop the boat on the side of the road and turn back and try to find it. because there was no way I'd make it to Deming after turning around with the boat. Anyways, I had to go back about 3 miles to get the bimini from the middle of the road before going back. I decided to leave the boat, get fuel, and come back for it. The boat has a tracker so I could ensure it didn't get stolen plus i had 2 tongue locks on it. I made it about 12 miles before I heard a sound from the engine that sounded like i hit debris on the road, a message popping up that said speed limited, pulled over and kept the engine idling while I inspected the truck for damage and could see none. I turned off the truck to restart it and try to get back on the highway but it wouldn't crank. I called roadside assistance from the myGMC app and a guy called me to confirm that I needed diesel and was out to me from Deming in about 20 minutes. Fueled up, started, but had a check engine light so I brought it to the Chevy dealer in Deming to get checked out and ensure there was nothing seriously wrong other than running out of fuel. It was just some computer errors from running out of fuel, had them cleared, and left for no charge. Filled my tank at the nearest fuel station, turned around got my boat, and continued on my way after a 3 hour delay and made it to Tucson just in time for happy hour! Friday, I finished my trip to San Diego about 407 miles (655km) uneventfully despite temperatures reaching 118F outside. I was monitoring engine temp which was regulating well between 190 and 205 and tranny temp which kept between 185 and 203 depending on the grade. No issues at all with cooling or performance. Honestly the torque was really impressive on the 6% grade that stretched about 35 miles up and down. By the time it was all said and done, i averaged 12.6mpg for the entire trip although I was getting about 14-16 after I had the bimini top stowed in the bed on the truck reducing the drag of the boat. I had to put in about 11-12 gallons of DEF throughout the trip to top off my tank at the end. I found that the DEF gauge was not displaying accurate levels because when it displayed red Low and no bars it took 4 gallons before overflowing despite the tank being about 5 gallons. The range of the DEF was not linear. It showed 300 mile range at 5 bars but dropped to red and low almost immediately after reaching that point. I learned to go by mile range not necessary gauge level and just fill up at the 300 mile range message. I am satisfied with the fuel economy i saw and was very satisfied with the performance and power available when needed thanks to the diesel. Overall very satisfied with the performance of this truck as I have had no issues with the drivetrain (knock on wood). Feel free to ask me specific questions and I will answer them as soon as I see them!
  24. Hey there i am having an issue with my brand new 2020, I installed my new snowmobile deck and connected it through the camper connectors built into the bed using the 4 pin connector and i have tried a 7 pin adapter too. The LED lights on my snowmobile deck turn off and the DIC says trailer disconnected when i press the brake and or use my turn signal. Functionality is restored once i remove my foot from brake or turn my signal off. I need to be towing a real trailer 14000lb and i cant now with my new shiny truck. Frustrating to say the least. I traded in my 2012 and it handled the snowmobile deck just fine with full functionality 2 days ago. PLEASE HELP.
