Grand Hauler Fender Rub?

[sassgrunt]

My first thought was for you to remove the parts that are causing the problem and raise the legs manually, but that kind of defeats the ability to hook up remotely. Maybe if you use countersunk screws that go through the parts into the bed, the shorter height of the screw heads wouldn't show above the surface of the plastic, (and therefore rub the top of the fender).
