safe lockup of AS at campgrounds

[J Goertzen]

I hope the webmaster of this site knows where to put this request,I am not sure if this is the right place. What is a good way to lock up your AS at a campground while you are away hiking,maybe for a few days? I don't mean the doors and windows, but how to lock up your rig so no one can hookup to it and drive off with your AS??? I have a small trailer hitch lock that goes through the hole in the latch you use to tighten down on the trailer hitch ball, but that does not seem enough. It locks with a key, but I bet a good bolt cutter could go through it. I thought I heard of something that locks the wheels. I also heard of some item called rotochock, but it sounded more like something to keep your AS from rocking and moving while you were inside and not much of a lock. What do you folks do??? Would hate to hike around for a few days to find the AS long gone. My AS is a 22' International CCD, 2003, thanks,Jim
