RZAR66, I had always 'heard' the brackets were interchangeable. Comparing the 1st picture Bedlam upload with mine, I would also have some issues. If fully folded in 180° motor might hit, but more importantly the jack foot WOULD hit my Torklift mounts?.
Took a bit of looking, only pic I have that shows jack inboard. Scaled it up a bit but should see head isnt square to camper. Never checked, its more like 130° folded in from out position. IF motor hitting was your only problem I would cut another set of parking notches.
Looking at Bedlams second picture, Im not understanding the function of the set screws on the pivoting jack side of brackets at all. Ours pivot freely, though my locking tabs are deeper. I cant imagine, I mean it would take quite abit for the jacks to jump up & out of lock slots?
I sure cant imagine having to thread those every time I pivoted the jacks in or out. First I've heard anyone mention that was required on the Rieco mounts...Bedlam do you also thread the set screws locking the jacks?
It also appears the interlocking slots are square cut, ours are tapered? Does that cause problems as far as engaging if not perfectively in line or is there something else that aligns.
Curious design...Ive never looked closely at the HJ brackets either.
