We have a 2019 Keystone Cougar 30 rls 5th wheel (34 feet) and tow it with a 2012 Ram 3500 4 Dr, 4x4 6.5 box. Truck is rated to tow over 16000 # and our rig is about 11.5 to 12k loaded. Truck toes and stops great. I use tow mode and on hills also engage the factory engine brake (jake brake).

I’m averaging 9.5 to 10 mpg. My 2015 Thor Hurricane gas class A averaged 6 to 7 mpg.

But with only a 34 gallon diesel tank I am starting to look at a 50 gallon replacement diesel tank underneath the bed.
