In a previous toy hauler, I used the existing front D rings to hold the Condor Wheel chock down. I made an aluminum angle (3" X 3") long enough to span the D rings, then cut slots so the rings stuck up through the angle. Bolt the angle to the legs to the chock and it's done. I put the hooks on the tie down straps through the D rings so the angle couldn't lift up off of them.
