A.JI rode with Charlie Campbell last year in his Cummins. You couldn't even feel his trialer behind him. I'm looking for a Duramax to be honest. I'm a chevy kinda guy. Thanks everyone for the input!!
do the research w/o brand loyalty and see if anything used compares to either a ford with a 7.3L or a dodge with the 5.9 cummings for reliablity and MPG.
the newer diesels( i think around ~05 and onwards), having to meet tougher emissions do not get the same mpg that the trucks from prior to ~'04.
