This is a replacement rear bumper for the Trailfinder 2 and Trailfinder 2 XLWB with Mojave body and AMPro chassis extension. This will mount to the truck's original rear frame with the two screws that were originally holding the plastic rear bumper mount and then is reinforced by slotting into the holes in the brace for the rear body mount. This will require painting and prep.
For the LWB with Mojave body, please see this one: https://shpws.me/SXA1
