I am considering getting a 2500 over a 1500 primarily so I am not limited to what travel trailer I get. While I am not planning on getting anything much over 30', even in the 25'-30' range the tongue weights can be at around 1,000 pounds and I just think I would be pushing it on payload capacity with a 1500 once it is loaded up with my family and some equipment. I saw where the 2500 has coil springs and the 3500 has leaf springs so I am wondering if the ride is more similar to a 1500. I would get the gas engine too because I wouldn't be towing that often and never plan on towing a huge 14k pound trailer or anything like that. If it rides pretty similar to a 1500, and it looks like it has the same dimensions, then I don't really see any downside to a 2500 except maybe a few MPG.
