whats your favorite diesel pickup
89 Cummins 4x4, 5-speed with 3.54's. Love the truck. It is good and reliable, and the WORST mileage I have seen is 16 MPG-towing. I don't get the 25 MPG other owners claim, but 20 MPG is pretty easy. Stock pump, and a BHAF and 4" exhaust. Stock tires and decent driving habits.
The weird thing is that it gets the same or slightly better mileage than my DD, but my DD is quiet, smooth and so I use it most of the time.
The Cummins is the ONE vehicle that I won't sell. Every toy will go before it does.
