battery and thieves
In my uhaul truck I made the battery tie down or hold down bars if you will, secured with a second cover. the batteries are tied down with bolts and on top of those is a pad lock bar over them, then on top of the batteries is a cover that is secured with locks. then there is the door .... so you have to go through three sets of lock downs to get the batteries..... I did this after loosing two sets of batteries in that truck... You cant keep them from stealing them,,, you can make it so cumbersome it is difficult to do,
or take the batteries with you.........
