Read between the lines...
Numerous NC airports suffered avionic thefts by 'airplane system knowledgable' person(s) recently.
I guess that omits all RVers as their cruise range far exceeds one state.
However, that does spark my following question..
Let's say YOU happen to be making a $100 hamburger run. (tied down)
As you return to your RV, you catch someone walking off with your avionics.
You look around, and there's nobody there but you and the thief...
"What do you do?"...
(that reminds me, I might need to add a pistol and small folding shovel to my W&B documentation..

)
