Huh captured carriage bolts...You could slot the hole that threaded portion of bolts go thru. At the mounts likely only
need 3/16 to 5/16" to rotate end of leg 1 1/2". Or split the difference between the 2 flanges. Drilling larger holes would
accomplish, I wouldn't, think load wise vertical height should remain.
Id lean toward slotting the square holes if mine. File top hole & bottom holes in direction needed, making square slots,
pivot on middle hole. Require disassembly but retain contact, non rotation of bolts while allowing jack to pivot.
I'd try loosening the 6 bolts 1st(not camper mount) to see if it would move.
As to capacity, simply replacing bolts, if that would solve and there is clearance between head and barrels would be easiest and first choice. A LOT stronger than a carriage bolt.
Slotting - that's brilliant. The carriage bolt heads are recessed, so slotting the squares would be too involved, but slotting the upper and lower holes on the brackets would be straightforward. Maintaining the same hole diameter (slot width) would also allow the carriage bolts to lock into the material, so I wouldn't need to use dowel pins. Sounds like the least amount of work.
Can you clarify what you meant about "try loosening the 6 bolts... to see if it would move"? No matter where I moved the jack prior to tightening the bolts, the round hole square peg arrangement always forced it back to the same orientation.
