If looking for a Ram 2500 get the soon to be released 8 speed transmission. It will be a fairly substantial improvement all around. Mileage, acceleration, especially towing with excellent gear spacing, durability. I transport TTs for the Mfgs. 535,000 miles on the 8 speed transmission only fluid and filter changes.
fwiw a double axle box TT towing 65 mph I'll average 14 mpg 15 with an Airstream in the 7,000 pound range that you are towing. I frequently tow 350 miles from Dayton Oh to St Louis MO on the little 26 gallon tank. I do have a tune which has been good for over 1 mpg towing. But if you are planning on stepping up to a TT larger than 8k wet the 2500 is a better tool for the job IE suspension axle ratings. Edit I have a Ram Ecodiesel. New 18s built into December are still available mid to high 30s OTD with a 100k warranty.
