Harbor Freight Motorcycle carrier

I had a frame mounted receiver on our previous camper where I used a single stinger basket to carry a 165# generator and some other supplies. It was rated to 400#. What failed were the welds on the basket due to the vibration and torque put on the single stinger. The new camper has two receiver tubes welded to the frame and basket has two stingers to eliminate the torque. Has made now over 5000 mile without a problem. I would have someone custom make a bike carrier with two stingers and reveivers to carry a motor bike, just my opinion.
