Hi Paul, I use a wheel clamp and hitch lock, the clamp is a "Clamp It" brand and they offer some sort of guarantee about theft! Yes the cable is better than chain but at the end of the day all of this is just a deterrent and will slow a theif down. If they really want it, they will get it!
Cheers.
Hmmm yes true, but with trigg lock, cable lock and wheel clamp i am hopeing that its just too hard!! Might also get a big angry dog and chain to the van? Could try the wife too... only jokeing girls!!!
