My Uncle was shopping for a 5th wheel RV in 2020, he was a lifetime Chevy 1/2 ton pickup owner. Well, once he got to looking at trailers he knew he should step up to a 3/4 ton truck. He ended up getting a 2500 Chevy with the 6.6 gas motor and man, he couldn't be happier. He pulls a 34ft 5th wheel all over the NE with the truck and it does excellent. I don't think it has the total grunt of a diesel, but with the 10 speed auto he has no complaints at all with it. Plus he gets better mileage empty than I do with my diesel. I pull a bit heavier than him and more often, so for now I like the diesel, but I wouldn't balk for a second if I traded into an adequate sized gasser that is set up properly.
