True, and I understand it will not be a superhitch -- no illusions there -- but I also realize a single 2 1/2 receiver hitch with 34" extension is also 'rated' to do more than what I need. So I figure this way we'll be more stable than that.
The superhitch is supposed to use the same bolt pattern as the stock F350 hitch so I don't think it uses more bolts. I may well be thicker though, but again, I don't think that's needed. My max towing weight is a tick over 4000lbs and tongue weight is very light (I'm guessing 150lbs but that seems heavy too).
