Happijac alignment issue
Hello campers, I recently installed Happijac swing outs on a 2010 EC850. When I extend the jacks while unloading, the foot of the driver's side jack sits 1-1/2" closer to the rear jack than does th...

...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.
The 3 bolts at either side of extension, between ext and jack and the 3 between ext and camper mount flange. IF there is any clearance of thru holes and bolt diameter, might gain a bit. By your description though sounds like maybe pretty snug. I dont know how tight the tolerances are. Going to take a small file to open hole horizontally without enlarging to much. Dremel would work but only 2 holes.
When jacks were bolted direct to camper flange was this 1 1/2" noticed?
Yes - there is clearance, and I can plumb the jack when the bolts are loose, but the square shoulders on the bolts force the jack back to the same orientation when tightened. I could eliminate the forced-centering by filing off the shoulders, but then only friction between the plates would prevent rotation - that's why I considered using dowels.
I never noticed an issue with the direct connection. The problem with the swing outs is the tolerance stack up: you have two additional interfaces, plus the slop in the hinge itself.
