In the next few days, I'm going to explore another idea I had... revolves around the "pop the transmission disconnect and push the vehicle out of the driveway/parking spot" videos I've watched. It should be possible to re-wire the electric parking brake module to only receive power once the vehicle is running (by switching a relay from the ASD relay output). I'll feed fuse #42 from this relay instead of the battery. So, when you want the extra roll-away protection, you'll park, set the parking brake, THEN turn the truck off. Unless the engine is started, you can't disengage the parking brake - good luck pushing a 6,400lb truck with the rear brakes locked. To disengage, you'll have to start the truck first, then you can release the parking brake.
