With my 1993 Chevrolet C3500 I had a bumper pull, 2 5th wheels, and an older large slide in camper.
Living in central Texas with small grade hills the slide in camper did the best with my truck.
My biggest issue was the small hills that we do have.
Yes, traded it in to get my daughter her first car.
I should also add that I drove that truck around like a rental car. I was not chasing better fuel economy.
My 2021 averaged 18, will try to post the specs below. Mine was an AT4 with a total of 6 inches of lift on 35" tires.

I had a 21 GMC with the 3.0. I am pretty sure it was the first gen model. The only issue I had with mine was the push to start or remote and starter would crank till time out without motor starting. It would then start every time the second try. I believe it did that about 6 times over the...
I just did my cooler, one of my lines blew a hole. Made a nice mess all over my driveway.
I did not replace the cooler. But I did replace everything else.
My fittings were one size smaller including the hose.
I kept my old cooler, plan on doing the fan one under the cab.
I just used Leroy's cooler lines and fittings. They worked perfectly!
If you don't know your size take pictures and send them to him. That's what I had to do.
