I made a huge mistake buying the old Cummins--it's 2WD and I convinced myself I "didn't need that." The gas truck it replaced was limited slip rear and it did OK nor more than I used it in winter or other adverse. But that damned Cummins --5 speed-- generates terrific torque and it does NOT have limited slip. It's useless in a muddy field or worse
The other issue with the Cummins is that I just don't drive it much, and it's also useless "around town" errands--going to the grocery store, it never gets warmed up.
The old Dakota might go away, too. I use it for "beater" errands but if much more goes wrong with it, it will go.
Regardless of "what I want" the prices are ridiculous
