Think inflation/ gas/ groceries bad? Try pricing used pickups!!

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
Well let the thing warm up before you leave. And I’m very surprised your 2wd Cummins 5spd didn’t come with a limited slip. Limited slips were standard in the Dana 70 and 80 that went behind the Cummins. Did you buy this truck used?
Also, you can get a limited slip easily for them
