Can't speak for the aftermarket pieces..... my choice came down to the structural integrity of the rear in the event of a collision. If the vehicle were struck in the rear, the force that would be transferred from the receiver to the 1/8 inch steel plate that’s bolted to the uni-body cross member and would simply, IMO, buckle like a cheap suit. OEM hitch is a massive piece of steel that, IMO, in the same accident would transfer the load to the structural longitudinal areas of the uni-body that were designed to take them.
