Cabinetmaker the extra circut makes sense, kudos on wiring it up and solvign yoru issue.
Another thing for all of us to check is how they wire the plugs. Most often they backstab the wire into the electrical outlet. In a home that isn't moving it might be ok (not my preference) but in an RV this can be a much bigger issue. I had issues with a couple of mine popping breakers. When I went through the RV and changed from backstab to twist the wire around a screw and I stopped having issues.
It's also helpful to know which plug are on the circuit and which are tied into a GFI outlet.
