Pro Pride 1400 hitch - need help

I had to spend a fair amount of time working out how to get the jacks mounted in the same area as the gas tanks. For yours, I can see how it would be so much harder. Nice that Sean had the alternative for you.

If he says 50lbs, then there you go! I wouldn't second guess his specs.
Did he offer any opinions as to your problems? Are we on the right track about re-aligning the hitch head using the yoke bolts?
