3. Do the math. The pivot is limited to protect your fancy truck but then it really stresses the frame. Again, do the math.
You made the claim, no one else. So I figured you already had some math to back up that claim.
OK here is results of some math I did. For a conventional unconstrained GN ball mount, 22 inch bed height, 6 inches of clearance between truck and fiver and an 80 inch wide bed. Angular difference between truck and fiver can be a max. of 8.2 degrees before contact. As I recall, side pivot fifth wheel hitches are limited to 5-6 degrees, just enough to protect both vehicles from damage. It would take a lot more work to determine, but I believe truck and trailer suspensions will provide several more degrees of tilt with minimal stress on either frame. So, the same real world capability w/o the possibility of damage.
Interesting side note, my gut judgement was that the Andersen Ultimate with it's raised ball mount would provide more angular tilt. Not so, it calculates to the same 8.2 degrees.
But regardless, anyone needed more than 6-8 degrees needs a flat bed truck to utilize the greater side movement of a ball mount.
