So I'm planning to replace all my door lock actuators. I'm also planning to build a cargo tray for the rear hatch. I had a thought the other day. it would be much harder for someone to access the contents of the cargo draw if they can't open the rear hatch. My guess is they'd break into the front in order to use the auto door locks to unlock it. So, i'm thinking of adding a switch to the rear door door lock actuator (somewhere in the rear of the truck) so that the actuator could be disabled. then, really the only way to access the hatch area would be with a key. of course, i'm sure if given enough time they'd try a screwdriver in the key hole, but by then, i'm thinking a thief would likely move on.

i'm considering traveling to mexico and further south and would like an area in the truck that's a little more secure.

what do you think? anyone done this? any red flags you think would be a problem?
