We are also in a storage lot. Our previous 5ver was broken into 3 times. The 1st through the window in the door, 2nd through the window on the driver's side in the rear and the 3rd, they used a crow bar to open the door.
We finally got wise...after the 2nd break-in, all electronics are removed and/or secured. Even have to remove my razor - yep, they stole that too during the 2nd one. The 1st time both televisions, a CD weather radio, sound system including the DVD player, a pair of gym shoes, the 1st aid kit, a bottle of water (found blood in the unit so presuming to clean the wounds). The 2nd time, both televisions (one was mounted & they broke the tray), tossed a mini-fridge around, razor and stupid stuff. The 3rd time, not much of anything but they did "toss" the unit.
We have looked at items but they either require electricity or going down every several days (maybe once a week) to charge/replace batteries. Will be following in case something is found!
