While battery theft seams common sometimes I rarely hear of it from campsites. I had mine stole a few years ago from the front of my house. Funny thing is I had just gotten back form a hunt, and had my Charger on them to completely top them off before putting the TT up for the winter. I came out to go to work and saw the leads hanging down. They took the Batteries but left the charger. I know have a nice metal truck box that locks. In my box I could place up to 4. Right now I just run 2 6 volts and the other half of the box of storage of things lime my chalks.
