This is my exact truck too. I hooked up my 6500lbs RV with 600lbs tongue weight and got 3.75" sag even with distribution hitch. That's ridiculous. I put the firestone airbags on the next day (airlifts were all backordered) and she sits level now. Not sure why people are so against the airbags, the have bounce joist in them and solve the level problem. They dont increase payload or anything and the smooth out the ride when hooked to a trailer or with heavier payloads.

Both my buddies with the 2.8 Dmax had all sorts of sensor failings on them, both traded out, one to the v6 colorado and one to a raptor. Both of them drove long distances for work and for weekend activities including 15+ highway miles) think its the 2.8 design/sensor product problem and not the way people are driving them.

I own a 7000lb RV and tow 2-4 snowmobiles all winter long (3000lbs max). Ive owned LLY, 2 LBZ, and multiple Ram Hemis. My commuter car for years was a jetta TDI with a chip. Loved that car. Ive wanted a 1/2 ton diesel for as long as I can remember. The 2500 were overkill for my needs and never got good mileage. They rode rough and never fit anywhere easily. So I wanted a hybrid of a 3/4 ton truck and my jetta TDI forever. The ecodiesel came out and was a great first step. GM had the small diesel in the colorado, but couple of my friends got it and had all sorts of issues with it, they traded in for the V6 gas version. Enter the 3.0. Inline 6. And everything else I wanted forever. I jumped on it for 2020 after waiting 1/2 year to see of anything really bad came up. So far its filling that dream ive had forever.

Im in the same boat, I want to run 300-400w inverter in the bed to charge my ebikes while driving, torn between wiring the 12v in the bed and plugging into that or just wiring the inverter straight to the battery. Id like to hear what power you have from this plug (15 amps?) or if I should just do my own straight to the battery (inline fuse of course).

3.23 I would have loved the 3.73 but by the time I was buying a truck I couldn't find the configuration I wanted (front bench, standard box, CC, elevation) with the offroad diesel package and the 3.73 gears. Something has to give and it was the gears.

I went with the firestone. Ive been an airlift guy for years, local shop gave me a deal on the firestones. So far they are just as good as the airlifts on my other trucks. The ride with 10psi does not seem to be as bouncy. I have the rancho shocks on the x31 package and they tend to bounce a little unloaded. 10PSI seemed to give me a more planted feel. If that makes sense. Imagine trailers are so nice. Fit and finish wise we love it. The heater leaves a lot to be desired, their only weak spot IMO. Wish they made a 26 foot BH model, I think we may downsize to the 2400BH just to have something a little easier to fit in the driveway and backwoods.

2020 GMC Sierra 1500 CC Standard bed Elevation X31 with 3.0L Local inventory was shot and depleted. Dealers all wanted Full MSRP on the Duramax. Best deal I could find locally was 51k OTD. Ended up finding one in wyoming for 42k and was out the door for 46000 and 2.89% for 72 months.

2020 GMC Elevation CC Standard box x31 (3.23 gears). 2500 miles now. Installed the autostopper first thing. best mod to date. 22 mpg around town taking kids to school/grocery run. 28mpg at 80mph on freeway work commutte (80 miles round trip). Best ever over 50 miles is 30.8. Both my wife and I love driving this truck, its quieter and funner to drive than our 2019 traverse (autostop, shitty 8 speed, but the wife gets what she wants...) Towing: I have a 32 foot RV, 11 feet tall, with 6400 weight/600 tongue. GVWR 8000. (imagine 2800BH for curious) By the time we load up with all the camping gear, dog, 2 kids, bikes, etc were right at or over GVWR for trailer and max or over on towing weight, I do run a distribution hitch. But my wife takes the literal mobile home seriously and we have all sorts of useless ****** in the trailer because she might need it... I had to put airbags on the truck after the first camping run. 3.75" of squat without them (6 pedal bikes in pickup bed). With the airbags the truck tows like a freaking dream and 0 squat. (45 PSI). Ive even found that 10psi in the bags seems to run smoother than with 0psi in them and no weight in the bed. I live in a state with 80mph freeways and 10k foot passes and steep grades. Ive been averaging 12 mpg pulling the trailer. My 6.6 LBZ duramax never got that pulling the same RV. Ever. Wasnt even close to that. My 2014 Ram 5.7 hemi was lucky to see 8mpg. She typically runs in 9th at 1800 rpms but always down shifts for an sort of an incline (like an overpass) at 80mph. I've pushed the truck towing to see what it can do, I wanna know its limits. She sucks the DEF fluid when towing but she doesnt back down from any grades or temps. Last weekend i pulled a long 8% grade on a state highway at 90 degrees temp (roughly 5500 ft above sea level). Tranny temps stuck at 205 and engine just above 210. She wouldnt hold 75, but tranny ran smooth and it ran over the top at 65 mph. The truck ride and performance with a trailer on is top notch and smooth. I did find that the sweet spot for towing my RV was 70mph. It will run in 10th at 1500rpm all day with hardly any shifting and i can eek out 15-17+ mpg Overall this is the truck I have waited years to own. Inline 6 small diesel with outstanding fuel mileage that can pull everything I really need it to. Its so quiet and smooth that my family loves riding in it, its spacious and roomy (my dog fits in the back seat with the kids, unlike my lbz or hemi crew cabs). Things I dont like: autostart/stop. Put the autostopper on (30 minutes to pull dash apart) and took care of that nonsense no part numbers yet to install the bed 120v outlet of 400w. I put ebikes in the bed as well as snowmobile gear and running a boot/glove dryer on the way to my destinations is a must. Was told this came on my truck, wasnt there when i picked it up, dealer has been less than helpful in making it right. Interior was not as nice as the ram, but the 3.0 drive and ride was much better IMO, hence I ended up with the GMC. no wireless apple car play cupholders are for childrens sippy cups. nalgene and hydroflask are way too big. Make some big cup holders GM. You can always buy inserts to make them smaller. silver lug nuts on black wheels, chrome elevation badges need to go. The Ram night package is about as sexy as it gets for style. GMC needs to get it together. 24 gallon fuel tank. There is room under there for 32 gallon. give us what we want DEF consumption while towing. She is thirsty, 3-4 hour drive towing your going to fill up with DEF somewhere along the way home.

Looking at these clean debadged trucks... i suddenly notice the glaring silver lugnuts. Why GMC? WHY? Gotta upgrade them nuts now boys. Ive got plans to plasti-dip the elevation badges black, not sure what to do on the Duramax badge. Thinking carbon fiber vinyl for the GMC logos and replacing wood trim inside with carbon fiber as well... Not sure what to do with the x-31 badges... they be a giant pain to plastidip...
