Bummer about the rim Nic. Spray the hitch with what ever you have and let it do its thing, ie give it a spray each avo after work then next weekend go and find a good tree, attach a strap to it with the tongue and drive away. DO NOT USE A SNATCH STRAP, I can't stress this enough!! And don't be silly about driving off at speed. A nice straight pull should see it should just fall out.
