  1. 06 Silverado 2500hd 6.0 My Silverado is getting really hot while towing up hill, to the point that the "Engine Coolant Hot" light is coming on. (Which I stop and let it cool down). This has gradually gotten worse. Truck does not get hot while towing on flat terrain. Any ideas?
  2. I've already installed the load lifter 5000 air bags. My compressor came in today and will be installing it tomorrow morning. So far I can say I really like how the air bags mounted in the trail boss. I should have a short review tomorrow after the pump install as I'll be towing a 6000ib tractor for a quick job at my buddies house
  3. Hey all I'm wondering if anyone has experienced anything similar to my ordeal? So I have a 2020 GMC Sierra 1500 5.3 V8. It only has 1500 miles on it and we just pulled our camper with it which only weighs 4500#. It pulls fine doesn't squat much and I use a weight distribution hitch. We took it to the campsite unhooked and I parked the truck. The next morning I started up the truck and the service engine light came on. After about 5-6 starts it cleared and is no longer on. It seemed to drive fine even when the check engine light was on. I'm wondering if me parking the camper going forward and reverse a few times made the gas mileage so bad it triggered the warning light?
  4. 2019 Silverado 1500 z71 with 8K miles, 3.23 rear, 8 speed. Today I have towed about 8000lbs of cattle and trailer. I prior towed an old farmall tractor back. Both times when towing over 6000lbs, I had the transmission in L6, tow haul mode. Sometimes when taking off from a stop, it almost felt like the truck started in 2nd, not dropping down the first. Would it do that? Or is the torque converter just being floated as RPM's rise, and possibly I am not feeling the shift from 1 to 2. This transmission is crazy smooth compared to my 6 speed. Truck drives great otherwise. Ran it to town empty later, no issues. Even ran it thru the Low mode gears, and it starts in first normally. Thought maybe this was towhaul mode trying to avoid unnecessary shifting if still rolling. Transmission running cool, never over 180 even with that load at 60-70 mph. Thanks for sharing your experiences.
  5. I just bought a 2018 Silverado LT Z71 with the 5.3 in it. I know max towing capacity says 11,100 lbs. I’m curious if you guys can give me some knowledge on what a comfortable towing range would be. Thanks!
  6. I tow a 21 ft bay boat with 1500 sierra and need to add rear suspension kit / support to keep the rear end of the truck from squatting down. what is available that will not void any GMC warranties, etc?
  7. 2020 2500 Duramax. Is anyone else having problems with their trailer lights? I’m having problems with the lights on all but one of my three trailers. Left turn signal and brake is not working. Took it to the dealer and they gave me some bs about how the truck can’t run led lights or more than 10 amps and blew me off. So essentially my brand new truck I bought for towing can’t tow a trailer with more than two tail lights. One of the two it isn’t working on is led and one is not and it runs the led lights just fine, just not the left turn or brake on both.
  8. Well, I've done it now... I've just committed to our RV rental for our next vacation. We want to try it out and see if this is something we enjoy or not. I need to add a brake controller to the truck. I'm planning to get the Tekonsha P3, but am open to other recommendations. My question is about the truck, though. Are all the trucks pre-wired to accept a trailer brake controller? Is there an RPO code I can look for?
  9. Hi! New here, first post... a question... I tow a small camping trailer with my 2017 Silverado 1500 LT 4x4. I've been under the assumption that the camper battery charges through the 7-blade connector while being towed. I'm just wondering if anyone can confirm this is happening or if I need to upgrade something to make sure. I've read a little about "low voltage / smart alternators" that may interfere with this process, just looking to understand for now. Thanks! Ernie in Southern Wisconsin
  10. Hey guys hoping y’all could give me some insight on the custom trail boss 5.3 6 speed 3.42 gears with it’s towing if anyone has this model and tows with it let me know how it felt to y’all. I’m going to tow my buddies jeep Cherokee to His home state which is about 700 miles. Will probably go through some hills and mountains in TN. Does the the power train struggle with towing because of the 32 inch durratracs?
  11. We are upgrading to a 2020 GMC AT4 HD 3500 and should be delivered soon. Asking $47,000 Follow this link for additional photos Facebook Marketplace ad So...Look no further for your next tow vehicle! Tow in style, tow with confidence!! This 2015 GMC Denali HD 2500 in Black Onyx has all the bells and whistles and more! She has only 52500 miles on her! This truck has been upgraded with BlueOx Gooseneck Hitch, a Second 7 Way connector in bed to secure your Gooseneck or Fifth-Wheel camper trailer wiring harness to help you tow in comfort and with confidence. It has also been upgraded with a Pop-A-Lock remote lock actuator for tailgate (unlocks tailgate when you unlock your truck). To help with those horrible GM headlights, this Denali has been upgraded with GTR Lighting Gen 5 HID 5000K headlights and Morimoto XB LED foglights...I cannot begin to tell you how much of a difference this has made! For just that little bit of oomph or MPG, this GMC has also been upgraded with the Banks Ram Air intake and Banks exhaust with chrome tip. Upgraded Shocks to BILSTEIN 5100 series shocks at 43500 miles. A Banks AutoMind programmer, is available and negotiable with purchase of this 2015 GMC Denali HD.
  12. I'm new to this forum, and not a current owner of a GMC but looking to buy one; could use some input. My current truck is a '12 F150 Platinum with the ecoboost and max trailering package. I'd like to buy a '20 GMC SLT with 6.2 NHT and the trailering mirrors(I absolutely won't buy anything without good trailering mirrors). Unfortunately GMC still won't sell me one...had one on order during the strike then GM said parts are back ordered and cancelled the order. Now they trailering mirrors aren't an option anymore on the SLT. So, I've started to look at the AT4, because I can get the trailering mirrors and I do like the looks/lift of it better than the SLT anyhow. My concern is towing my 30' TT, with a dry weight of 6800 lbs, tongue weight of 880 lbs. The payload on the AT4 I drove the other day is only 1540 pounds(300 less than my F150). So I will be maxed out on payload with just the camper and people, and getting close to max GVWR with all the other gear if I can pack it to keep the weight on the rv axles. With my F150 I've had no trouble loading a half bed of firewood plus all the other gear(thus probably overloading it as well), but I'm not confident that the AT4 would do as well. The AT4 I test drove the other day felt a little less stable than my F150(could be because of the lift/tires). Anyone have experience towing with the AT4, maybe with sumosprings/timbrens added on? Airbags are something I would like to avoid. I do use a wd hitch, and I only tow around Michigan so no hills to speak of, but my wife ends up towing the camper by herself quite often so I don't want to purchase a truck that she isn't going to feel comfortable in.
  13. Got a 5th wheel camper to pull behind my 2500 HD Denali with Duramax Trailer according to the title is 11,800 lbs Did not tow well on the first outing after picking it up . the truck jerked like riding a horse and serious lack of power like the converter or rear axle gear not allowing the motor to work as it should , truck did not squat that bad so I'm not sure what the problem is . Camper is definitely heavy but was not expecting it to be that bad . Air bags help ?? HELP !! Jerry
  14. I'm confused about what trucks are good for towing. Is there a BASIC summary of whether a 1/2, 3/4 1 ton etc is good for towing as to what limit is the GVWR of each rated truck. I know there are other factors to consider. I'm looking for just a basic starting point if there is such a thing. I want to tow around either a TT or 5th wheel between 26 to 30 ft. Of course different weight ratings. Example what is the maximum tow for a 3/4 ton. Ideally, get more truck than needed. Should I start looking at a 3/4 ton and then a 1 ton? What is the max that a 1/2 ton should even be considered. I'm looking to actually live in my RV full time for a year and maybe much longer. Being semi retired, I want some time off from a land based stick and stone structure and explore this great country. I'd like to buy used. What years and models should I avoid for towing? I don't want this to be a bad mouth GM or Chevy trucks. I'm asking for a reliable truck or even a SUV . I'm taking my 3 small dogs with. Long story, she is divorcing to find herself or some bleep. And I will not abandoned these dogs we have had for the last 10 plus years as she will do. So.... I want time away, and just some time exploring. Any help of truck to choose would be fantastic.
  15. Hey guys, feeling a bit dumb because I searched (old man disease), How can I tell if my towing package includes the electric brake control? 2012 extended cab 1500 THANKS !! Joe
  16. I know the 6112s are semi-new to the community. My question is what would be the lowest possible notch I can install these and still have enough clearance to fit 275X 65R 20 KO2s. I’d imagine the notch settings are similar to the 5100s accept there is 1 extra notch I believe. I have been searching online for the past week and cannot find anyone that confirms the lowest possible setting to fit these tires. I know I can install them at the highest setting and fit just fine, But I am trying to keep rake in the rear due to occasional towing and i do not want to add a leveling block to the rears. I was thinking the third notch (1.25” of lift) would work but I’m not sure if It will get rubbing. Does anyone have any idea on this? I currently have a 2.5 inch leveling spacer but do not want to install it when I switch to the Bilstein 6112s. Thanks!
  17. So I’ve been on the hunt for some quality tow mirrors for a while now and haven’t had any luck. Any of the ones I find on amazon either say they don’t fit my vehicle or the reviews are not so good and just nothing really promising that what I get will fit or work completely. I have a 2014 1500. If anyone else has upgraded to tow mirrors on their 1500 any links/recommendations/information would be appreciated. Couple pictures attached
  18. I've got a 3500 that I'll be using to tow a 5th wheel later this year. Right now I'm in the market for mudflaps. I'm looking at the x-long Duraflaps that will sit about 14" below the fender in the rear (leaving me 6" from flap to ground), which is fine and dandy. However, i'm concerned about when I hook up a 5th wheel, how much that 6" will be decreased. Those of you who drive a 2500 or 3500 that tow a gooseneck or 5th wheel - about how much have you noticed the rear lowering? I know it depends on the weight of the trailer, but i'm looking for some ballpark numbers. I'd hate to buy these x-long flaps that end up being 2" off the ground after hooking up the camper.
  19. I'm sure this topic has been overplayed, but I have looked through many of the topics and still haven't had my question answered, so here goes. I have a 2014 CC Silverado with a Procharged 5.3 that has an Air Lift bag system with an onboard compressor. Clearly I have some use for this truck outside of mere daily driving. In fact, I tow a small fifth wheel on Florida's relatively flat roads (fully loaded @ 9k and 1,300 pin weight) about 7-8 times per year for local camping trips (less than 200 mi.). I have no complaints with the truck's performance in any way, but it is time to look at changing the brakes, and I would like to upgrade to a reasonably priced high-quality brake system geared towards a towing application. I have tentatively settled on a PowerStop Z36 4 wheel system and wonder if anyone has any experience with them who tows a "heavy" load such as I do. I appreciate any feedback, David
  20. I have a 2017 Chevy Silverado 3500 HD High Country with 6.6 diesel equipped with tow package. It has dedicated trailer brake and trailer fuses within the primary fuse box under the hood. My passenger side trailer blinkers and brake lights are not working. I've traced the lack of 12v power all the way up to the 10a fuse dedicated to the right side trailer brake/signal light (fuse #17). I have replaced the fuse, re-tested, and still no power. The left side trailer brake/signal light (fuse #14) has 12v power going to it, tested on the top of the fuse when the flashers are on, but the right side has nothing. I've also swapped and then replaced the trailer parking lights relay switch (relay #63) and still nothing. Is this most likely an issue with fuse box or something else supplying power or ground to the fuse box? Thanks for the help... this is the craziest thing.
  21. I've towed my horse trailer with a 2003 Silverado, 2007 Silverado and 2011 Silverado with no issues. I purchased a 2015 GMC Sierra Denali and suddenly was receiving Check Trailer Wiring error messages, WITH dinging bells, over and over and over and over. Had trailer wiring checked, electrician said trailer was wired correctly the problem was 2015 wiring. Few months later, I acquired a 2015 Silverado. Same thing, Check Trailer Wiring, with dinging, over and over. Sometimes you go miles with nothing. Sometimes it starts when you pull out of the drive way. This does not happen when I use the smaller flat plug for my flat bed trailer. Only when using the larger round plug. Took to local mechanic and they could find nothing wrong with trailer or truck wiring. They thought it only happened when brakes were applied, but this is not true. They finally said they could not resolve the issue. The trailer then went to a trailer dealership, that sales the brand of trailer I have. Their initial checks on diagnostics showed no errors. I left, the dinging started, I went back. They rewired the trailer, replaced the brake box and have no idea what else to do. Picked up trailer today. Dinging took awhile, but eventually did start. They asked if I had the truck rewired by the dealership - no. Nothing. It's happening on two 2015 GM trucks. But has never happened in the 13 years I've owned the trailer. Help?
  22. Hey guys so I have a 2019 Silverado 1500LD with a 3.42 rear end with 11k on the clock. I've been noticing that my engine or coolant temp goes passed 210F but when it hits the next 1/8 gauge stick it goes back down passed the middle mark to 190°F. Is that normal for 7000 pounds uphill towing in 95°F weather. Talking about the 5N grapevine in Cali for those who know the climb.
  23. Hi guys, Over the winter i bought some 33"tires (275/60R20) to go along my 2016 Sierra Elevation.. this truck has a 5.3L and 3.42 gears ...during summer time i usually pull my TT that weights 6350lbs dry so knowing myself it is usually at 7500lbs full so lets make it 8000lbs for worst case scenarios ... I have a 6L-80 Trans 6 Speed ... So my question is; will it be that much of a power loss with the 33's on ... I mean this truck can pull 9200lbs as per the dealer specs .. but that is on the dealer tires i had last summer ...i didnt even think about the loss of power it may cause ... But i had so much of a deal on the BFG KO2 tires ... I couldnt pass on ... Now im uncertain of what i have done as the tires and installed on my rims and just waiting to bolted on ... Thanks for your help !
  24. My 2017 Denali rides rough when pulling my bumper pull camper and since it has Magna Ride shocks I can’t use most options. Torklift brand inserts between the leaf springs and the overload spring has been recommended as the solution but is expensive. Do any of you have experience with this method? It looks like a simple solution but I would hate to spend over $300 for something that won’t fix my problem.
  25. Does anyone on here have one of these dump trailers? I’m thinking of getting one for hauling mulch and gravel. I like that it has ramps and I could put my tractor on it. It’s around $3,600 which is about average for this size trailer. http://extremeroadandtrail.com/66108.php
