Tuner might just be the difference? Also, for the life of me I dont know why you might have a GMC, after all, your screen or ID name on here has Silverado in it, I'm just not with it today.
Wow, your fuel mileage is better on your truck than my Chevy 2500HD. The best I ever got on the highway was 22.8 MPG, that was some 55 mph to 65 mph driving flat ground, no mountains. Generally on the interstate running about 70 mph, I can get from 19 to 20 MPG all day long, that's about it...
A 1500 Chevy or GMC with the 3.0 Duramax really does interest me, as far as a daily driver lite towing truck. Changing the oil pump belt at 150,000 to 200,000 miles really doesn't bother me. Heck, no more than I would be driving it, that would be 15 to 20 years from now, I'd be in my mid to...
Yes Sir, great eyes to catch that, I didn't read all of the article. Amazing how social media and news media gets things wrong on a regular basis. We could try and correct them, sometimes they claim to know everything and don't give a big rats arse if the information is correct or not.

I know @BoostN, will give us his fuel mileage in due time, nothing like real people’s experience. Here’s some reading material, I think it mentions a highway mileage of 29.
Nope, the 5.3 can tow up to 11,000 pounds, the 3.0 diesel is at least 13,000 pounds. 6.2 gas is 100 or 200 pounds more than the 3.0 diesel, all according to the configuration of the truck.
GCWR for the 6.2 gas is 19,100 pounds.
GCWR for the 3.0 diesel is 19,000 pounds.
My findings based on...
I don't personally know anyone that owns one, but I see a few now and then.
There was alot of discussion about the oil pump belt having to be replaced at some point. Latest info about that (newest engine design) is replace it at 200,000 miles or at 15 years, whichever comes first. I also read...
Towing test, if you are into watching the TFL Ike Gauntlet test.

Also found this info, don't know how accurate it is. Possibly the heated seat fuse is the same one for the ignition?

Wished I could help you, but my 2006, Chevy 2500HD is not a luxury model, :D therefore I don't have the heated seats. I would be looking for a fuse to pull or try what smokymtn65 recommended.
Sounds like you are making progress. You mentioned the camper being like a wind sail, yelp I agree. My 21 foot camper probably weighs 4000 pounds or so. With my Duramax, flat lands, I might get close to 13 mpg if I drive decent. In the hills and mountains, It's in the 12's, I did see 11.5...
