I just bought a 2011 Ram 2500 CC CTD 4x4. I do not expect any problems pulling my 2011 Silverback 29RE. I have pulled over a year with a 96 F250 7.3 2WD, never had any problems going or stopping! The Ford only squatted 1-1/2" with everything fully loaded for a week of dry camping at The Rally last June in Louisville. I do not expect the Ram to be any different in the squat. I do expect the Ram to run like a greyhound given the extra horsepower and torque. Went from 235 HP to 350 HP, from 525 torque to 800 torque.
My only concern is bed height. I probably had about 8 inches of clearance with the 2WD ford. This 4x4 Ram is considerably higher at the bed. I do not want to run down the road with my nose in the air, so it will be interesting to see if I can get the needed truck to nose clearance without being stuck up.
