I had an older Arctic Fox 1140 that had the exact same problem. That particular one was an '04. Arctic Fox in their infinite wisdom back then anchored that tie down to nothing but a sheet of plywood. There was nothing else in that corner, no framing, no solid piece of wood, nothing. IMHO it should be a factory recall, because it could fail going around a corner, and **whomp**, there goes your camper.
My work around was to go from the weakest point on the camper to the strongest - I put eye-bolts on the camper jack brackets and used that as the tie-down mounting point.
Then I made a much more permanent fix and got an Eagle Cap. ;-)
