when I lived in AZ, my bride and I were driving truck OTR. So we were home only a couple days a month. I had a 30x60 garage with all my trucks in it, and someone broke in twice.
The first time they tried to siphon all the fuel out of the rigs (the Toyota, the 3 wheeler, and cut the fuel fill line on the bus) but left the old F-250 alone. Bad part was the Ford was the only one that had ANY fuel in it. Full tank as a matter of fact, BUT it had a locking cap...Umm, the cap key and the ignition key were in the ignition the whole time!

The second time a few months later we came home and the garage doors were wide open. My poor F-250 was across the yard and buried in the wash behind the rear gate. Called the sheriff, blah blah..
Figured out they tried to steal the Toyota (didn't run at the time), then the bus (again, out of fuel and no battery!)
They hot-wired the F-250 (I took the keys that time!) and drove it out of the garage and headed for my back gate. I wold have loved to see the look on their faces when they hit the brakes to slow down...There were NONE! I had taken the MC off to replace it before we left that trip. My HIBOY truck was buried in the sandy wash up to its winch bumper, and left for dead. I put the battery back in the tray (bungee cord broke on impact), shifted it into 4wd and drove it back to the garage!
Bad part was, all my tools, equipment, parts, everything was still in the shop. Not one thing was missing, even with the garage door open for at least 2 WEEKS!
Sorry for the long read, I have a few other stories of bad people getting Karma when messing with my stuff..
