We currently have 2 enclosed trailers stocked with equipment. Security on the two of them has been a constant issue on my mind lately. I don't really believe in the ball/hitch locks necessarily...basically I haven't seen much in the form of a "lock" to secure these from theft. I recently read in etw's equipment thread about GPS being installed on enclosed trailers. I've done some minor research but have not come up with much info. Does anyone currently have this installed on any of there trailers? Any info on price...installation...where you got it...monthly costs or a one time charge? I don't really know anything at all about GPS but I do think this would give us the best oppurtunity to retrieve our setup if it was stolen.
