I added an outside outlet -- mounted box inside, then used regular exterior cover plate. Don't have any leaks
, but also don't use it much at all. I put it back in since it had one there, but I think I have used it more working on the camper in my drive (rather than get out one more extension cord) when I needed something and the camper was already plugged in. I might use it more as time goes on, but use gas for cooking outside, and cordless drills etc for any tools I need while camping.
