Well let's see what else we can can come up with. While it is at your house I can get your sewer hose, and your battery, but the most expensive and easiest to get rid of, besides the battery, would be the wheels and tires. In case you have one of those expensive electric tongue jacks, that could be mine also.
Now, let me be clear, I am not a thief, and hope never to be. Just wanting to point out there are a lot of things bolted on your camper that can be had in less than 30 minutes. Most, sewer hose excluded, worth much more than your power cord. Please don't read this and get crazy trying to protect everything, you can't, prisoners got out of Alcatraz didn't they?
Oh yea, the power cord is pretty much limited to an RV market. Battery, wheels, Jack, could be sold to much wider range of individuals.
