When I park in "iffy" places I often put this sign in my window. Who would steal a truck that needed an engine and transmission and had 214,000 miles on it?
In remote areas when I must leave my truck and trailer awhile, I leave a note on the door like
this hoping would-be thieves would think twice.
When I must park awhile on someone's property, I sometimes post a note like this to mollify the owner and explain my presence.
This is a motion detector which sounds an unmistakable alarm when someone comes within 35 feet of my rig. I stick it outside when I am in remote places. It comforts my sleep. (though once a passing coyote bolted me upright at 2 am)
This clever adaptation is useful in RV hostile parking lots, like some Las Vegas casinos. The long retractable eyebolt allows the door to open or close when in this position.
Then when it is withdrawn inside, it persuades any security guard that no one is inside. And I sleep undisturbed.
The palm of my hand is concealing a tiny piece of security which allows me to walk in otherwise dark and dangerous places with reasonable ease of mind.
I have other secrets which to reveal would destroy their usefulness. But soon I hope to photograph and share one of my cleverest---the wheel trick.
