If I power it off the trailer lights it will only come on when the trailer is being towed and I won't have another thing to plug in and unplug. I want it so I have a better picture of what is behind me. If the trailer had normal lights I would not have a problem but the trailer has LED lights that are new tome.
Yep... RVs are wired like houses, not like cars. Black is hot, white is ground/neutral (no separate ground and neutral). It gets to be confusing until you get used to it. Just remember that your RV is a "rolling house" and the wiring is just like your home. Once you get passed that, it will come a lot easier
My 2 cents, your mileage may vary...
