I was hoping for a response like, "AS left those out of the manual because everybody knows about those!" I'll get out the sniffer and fire extinguisher, plug them in for a few seconds and see if anything happens. I'm not familiar with "RV/boat heaters" and will research those so I know what they look like. I appreciate your input.
I suspect the cord in the front bedroom is a 110v element for the water heater. If this was installed aftermarket I will assume it's unregulated (won't automatically turn off when the tank is empty/hot) which is "bomb like" and under my bed. So I got that going for me.
Thanks for your time. I'll report back.
