Just thought I would share my towing experience with our new 2500 Hemi 4x4 crew cab. Our camper is a Cub toy hauler (the kind where the wheelers load on the front of the camper). Weight when loaded is ~7000lbs (wheelers, water, gen, gas etc..) Our 96 ram 1500 w/360 eng, while rated to tow this weight had to struggle to do it. I installed air bags to help offset the hitch weight (bumper pull trailer). I never did feel confident about making trips. and getting home again. So comes the new Ram 2500 Hemi. I really considered going with the Cummins but (for multiple reasons) settled on the Hemi. On to the towing experience. Our first trip was a shorter ~ 100 mile run one way. I will say that towing with the Hemi was a night and day difference. With a head wind of 15-20 MPH the truck in tow/haul and using cc set to ~60 mph and some smaller hills to climb the Hemi performed great. Gas mileage came in at 7.5 Mpg (calculated). Yes the tranny does shift on hills where the cummins may not. but for our purposes i have NO regrets going with the Hemi. Ride quality while towing with the 2500 was excellent even with air bags being pumped up to level out the ride. I wouldnt complain about the ride of the 2500 even when empty, just slightly more robust than the 96 1/2 ton (both are 4x4). I love the factory trailer brake controller VS the aftermarket cheapo that I installed on the 96. The controller is much smoother in brake application, almost proportional like. Should ad that the Hemi did not struggle when climbing hills with the cc on. I'm sure that there is some grade break point where pulling could be an issue but in Mn long steep hills are not much of a concern. Thats our first pull the next one will be ~250 miles one way
