I have a Dodge 2500 with the diesel. I don't really need the diesel but dang it's nice when hauling a load. For hunting, I'll hang on my 5k camper plus load a stock rack with 4 llamas in the bed. That will weight about 1700 to 1800lb and it has a lot of wind resistance. The camper's an old flat fronted one and it has a lot of wind drag, too. It's a m/t and I very rarely have go down more than 1 gear. If I do it's because of sharp corners where I have to slow down too much.
