GMC 2500 Hd 2017

Thinking about trading or selling my 2017 GMC 2500HD Crew Cab long box (8 feet) 4x4, 6.0 gas motor. SLE (Cloth interior) Bluetooth, traction/stability control, ABS, NAV. Built in Trailer brake controller, back up camera, remote start. Everything works as it should accept for an occasional check engine light due to the 02 sensors/catalytic converter as well as an exhaust leak. Just did plugs, wires, coil packs, injectors, MAF sensors and intake manifold gaskets. Has new rear brake rotors, pads and e brake cable.

Only thing I’ll trade for is a 4 door Cummins preferably manual(or second gen extended cab Dually must be manual) Or 17,500$ cash
I also have the running boards and a headache rack that could go with it.
