The Ram 2500 SLT 2dr long bed with the Cummins Turbo Diesel has been a great performer for me. Not one problem in over 55,000 miles of driving in less than 1 year. I average 12.5 mpg @ 68mph pulling 7x14 cargo trailer with avg gross weight of 4,000 lbs. (I avg 14.0 mpg when towing empty trailer @ 2,100 lbs) I have been across the desert, across the Rockies, and in a blizzard. The only negative with the 2 wheel drive is that in the snow,ice, or Florida sand, you are not moving...even with an empty trailer attched, there is no traction! Light rear end that will spin even with moist road conditions. Otherwise, I am extremely pleased with the workhorse that I bought from Dodge.
Improved traction for the 2 wheel drive in sandy/wet/snow/icy conditions.
