I you have a reason to worry about theft or vandalism while in storage...They will steal tanks, batteries, spare tires. They can break in thru the skylights and take anything of value inside. Heck, they can steal the whole dang trailer. Remember, the keys to the outer storage compartments are universal,(and easy to get into-anyway, key or not). Lonely TT are big, valuable targets to low-life thieves. IMO: I would try to find more secure, storage. Space in airport hangers, barns, etc. We have old mines, here that are used for storage.
