One other security tidbit. Any advertising on the exterior that relates to anything DJ (in some areas of our great land) translates directly to "Good stuff inside. If you have a drug habit, and are in need of quick cash, steal me!"
That is true. Would be thieves will follow you to wherever that trailer is parked and use crowbars to bust open the hinges, locks whatever. I have a van and i don't even like stopping off, except to buy gas, on my way to or from a gig.
