What's it worth? Cummins tow rig
Generally 2wd, auto, cummins trucks go anywhere from about 3k to 6k depending on condition, mileage, etc... that sleeper setup kinda throws a curve ball at you, it's a very specialized body so it's hard to say if it adds value or hurts it. I'd say barring any major mechanical problems 5k to 6k would be a fair price range for that rig.
