All kidding aside I have seen one dude had one of those fence chargers hooked up to the frame of his RV trailer...
Of course in todays world you would be the one that goes to jail for hurting the thief...
All I can do is just keep everything out of sight the best I can.. Anything important to me is secured and under a lockable hard folding cover in the bed of my truck and goes where I go... I have motion sensor lights come on when I leave my trailer unattended but of course that probably just gives them better light to work with...
darn shame....
