Interesting Paul, I guess if its a tight fit unlike the pin that goes through it would cut down on the wobble. I was contemplating this Hitch tightener: no wobble, anti rattle stabilizer device for hitch accessories
grips the receiver all the way around...but honestly... the ratchet straps might look "ghetto" lol but it stops any kinda movement. I have a Cargo Management - Reese
weighs about 36lbs or so and I cut the square metal pipe shorter since my receiver is ontop of the bumper and it could only slide in so far before it touches my ParkLiner
... so Im sure it shaved 2 or 3 pounds off. I could take the poly part off and bolt my trunk right to the framework but I like that its a little bigger so I can use it like a table...and put my water jug on it.
