I went with 1998 Dodge 12V diesel 3/4 ton (single wheel) and put a Fleetwood Caribou, air bags and upgraded suspension and tires on it. I think I was pushing it at times, but the amount of time with no camper and single wheels was best for my situation. If the camper was going to be on all the time, it may have worked out differently for us. Of course the camper has been sold and is still in great condition and there was something special about the set-up on my Dodge as I sold it to a guy from Maine who converted it to biodiesel. Flew out here off of pictures and a pretty reasonable deal. Single wheels gets me through the drive in at "In-N-Out" when the camper wasn't on! Good luck!
