As an RV owner (3 different units), I'd go with a 3500 diesel for two reasons; the 2500 diesel is payload limited (mine is 2170 pounds). And you will surely upgrade to a bigger RV sometime in the future, as we all seem to do. The 3500 will have the necessary payload, and the Cummins diesel will pull most anything. I went through 2 other trucks before I got smart enough to buy the diesel. Just my opinion....
