This is an option I hadn't thought about!
My initial thought was to butt weld a 2” receiver tube to the box, but after thinking about it, I don’t believe that would hold up over time. Even if I added some type of gusset top or bottom. Then thought about sinking the tube into the plate and welding both sides, that’d be plenty strong. Here’s what I have to work with, top placement seems too high and plate is angled, I do have an adjustable height hitch I could make work. Still concerned about the angle. And lower position seems, well, just too low.
