do you need 3/4 ton? if not, Dodge and now Nissan have 1/2 ton diesels. One B in Law just took delivery on a new Dodge Ecodiesel 1500, time will tell how good it is.
Personally, I love a Ford truck. But I drive a Dodge 3500. One good reason...Cummins. Powerstrokes are good engines but if it needs almost any repairs, labor costs would kill me. The cab has to come off the truck. Whereas on the Cummins, almost any repair can be done with cab on the truck.
Example: One of my guys has Ford with 6.4 Powerstroke, the tensioner pully seized and threw the serpentine belt. No big deal right? Wrong. 4.5 hours labor at Ford dealership. So, we did it ourselves. First step, take off front bumper. Second though 8 step, take off and peel back 7 coolers between bumper and cooling fan including drain all the coolant and remove radiator. Finally you can replace the belt and tensioner in 15 minutes and commence putting all the stuff back on that you had to take off. This took most of a day in a nice garage. Imagine if this happened with the wife and kids pulling a camper somewhere.
This same job on a 7.3 powerstroke or Cummins is about a 1/2 hour job.
