I have a 2001 dodge dually (3500) with the cummins diesel (which is why I bought it). It has been a tough truck,but I take care of it. I have had some problems with the transmission and also the fuel pump for the injectors (both while under warranty),and some problems keeping the front end in line.Other than that, it has been a great truck. I also have a 28 ft dovetail flat bed trailer with tandem,dual 10,000 lb axles for hauling hay, equipment,etc. the trailer will actually haul more of a load than the truck can pull so I have to be careful about that. ;-) :cboy:
