I don't know if anyone has said this yet, but personally I think that team trailers put a HUGE glaring target on your stuff saying "hey, I have lots of valuable electronics inside of me!".
If a bunch of teams rented uhauls and flooded the lot with them, I'd imagine that it would have the thieves working long enough to catch them (maybe -- Thinking of probability here lol, feel free to comment other mathmatical deterrents here xD)
Remember, use the buddy system!
