Thanks for the good info.
No doubt a 3500 would be better at carrying a TC but I'm looking for maybe a good compromise.
I had an 03 Dodge CTD DRW for several years and carried different TCs from a 5200 lb AF 1140 down to a 2000 lb Lance 815. No matter what truck you have, carrying a 5k lb TC is a big load and will never handle like an empty truck. The 815 on a CTD DRW was actually sporty to drive even on mountain roads.
I don't want to get a 3500 and hate it as a DD because of the stiff suspension.
I may focus more on the Pop ups like the Northstar as I want something small, light and easier to get around with. I would only stay 1 or 2 nights in each place with this rig.
As mentioned, I have a 21' TH to use when staying for awhile.
I added airbags to my 1500 Ram with coils and that made a big difference, so I would think a 2500 with coils and airbags would carry a 2k lb pop up comfortably.
My local dealer is now advertising $12k off new 15s. I could get a 4x4 CC Tradesman CTD for under $38k.
