An anti rattle clamp would also do the job. If I get into one of those strange states that are on a tear about hitches on trucks, I might need to pull it off and put it on fairly often. That makes those clamps less attractive.
Given the drop on the shank I have, it will only work for a F-250 or F-350. Just about anything else will be to close to the ground. Since I only have one truck it's sort of a moot point.
Welding is another option. I'm not sure just what sort of steel this stuff is made out of. Epoxy is pretty rugged stuff these days and it would fill a lot of gaps a welder could not get to.
One could just go get a 3" shank. My guess is, I'd need a crane to lift it onto the truck ...
Yes, I just keep going around in circles on this. Fortunately Ford is giving me a *lot* of time to think. Delivery just got pushed out again .....
