I would bet the tube could handle almost any realistic weight. Its the plates and attachment method that limits the rest in my mind. Like a 1/4 inch plate would be good to 4500, a 3/8 6k a half to 10k ( pulling numbers out of the air ). Now I dont think welding it on is the answer either, as bolts can be as strong as welding when done with proper fasteners and amount of fasteners. Welding only attaches the edges, where bolting is thru out the contact area, yes this could be done with plug welds thou.
I also think a lot of the limits of hitches has nothing to do with actual weight, its more momentum than weight. 6k pushing straight the tow vehicle is a lot easier than 6 k pushing sideways when in say a tight turn to the right or left as your braking. it will try to push the hitch sideways, and that could bend the plates. I used to have an old 19 foot trailer that weighed a ton, the hitch I had on my pathfinder was only a 3k. I never had a failure, never had an issue with straight line braking but even with trailer brakes I did jack knife one day on dirt when I hit the brakes in a turn.
