Have any of y'all ever sold scrap? Been to a scrap yard? There are always druggies there selling $5 worth of copper. Thieves will take anything. They have no problem slicing thru an rv plug with a steak knife, and chances are, they will not even get a tingle when doing so. If you are paranoid of it spoiling your trip, buy a spare cord and keep it somewhere secure for a backup if your primary was stolen.
And no, they do not care about the ends being on the cord and they do not take the time to strip the insulation. They will either sell it at a reduced rate with insulation on it, or throw it in a fire to burn the insulation off and get #2 copper price for it. I always have spare wiring around my shop, once I get enough to make it worth my effort, I make a small fire and throw all of it on there to burn insulation off. A smallish bucket of burned copper can easily fetch over $100 with current values.
They even occasionally climb the utility poles and cut down live high voltage lines to sell for scrap, so nothing you can rig up will deter any determined thief!
