I've thought about changing them out, but I really can't see going to the trouble. In my case, I have no storage compartments. No genset box. The battery box is the only I can see doing something about. Maybe the fresh water fill(if only for kids messing around)
Even then, if they want in, they'll find a way. Nothing a prybar and/or a cordless tool can't tackle. If they want to go to the trouble of taking my 20 lb propane tanks, they can have em. They really need to be finagled out. Not a quick thing to remove especially without a step stool.
My main concern is the entry door. I'd like to eventually get that keyless entry deal and somehow wire it into the truck alarm. Pricey, but worth it, maybe?
