I am going to place my order for a 2013 Ram 3500 DRW Crew Cab Diesel tomorrow.......3.42 or 4.10 rear end? Putting a 1140 Arctic Fox on the back, towing a 5,000 lb boat or Toyota Tacoma from time to ...
Get the 4.10. Been pullng with my Cummins dually 4.10 rear end since 2007. If i attempt to run at 70+ empty the fuel economy sucks the big one. However towing my 13,500 pound fiver I can run all day with the cruise control on and still return 12.5 MPG.
