Chevy express Towing U-haul flatbed w/ 4650LB trailblazer

For what a NEW hitch costs, get a new one. 200-300$

The 3500 comes with a 6.0 motor. Depending upon year, the 6 sp auto shows up first, IIRC about 06-07 models.

With a GM van, find one with the G80 locking rear option if you want a bit more traction. Should be on a sticker in glove box.
