2007 Ford F350

Bought this last year in Michigan to pull our fifth wheel, but never really used it. I have all records from the past owner and me. When I got it I put 4000 in 6 new tires, brake pads, rotors, calipers, shocks, tie rod end, serpentine belt and tensioner. Check engine light came on for glow plugs and number 2 injector, I had injector replaced, I did the glow plugs, module and wires when I moved back from Michigan 2 months ago. Check engine light went off for a bit then came back up, it's the pcm which is 250 brand new already programmed, I ordered it and its on its way. I just need to sell it, no use for it anymore.,  runs great, I don't want to spend any money on insurance payments anymore when i dont need it.. Ac blows cold, new trailer brake control module.
