Every motor home or camper van may seem to be deficient a feature or two. I purchased a Roadtrek 210P and I've made a few improvements to tailor it to my personal "tiny home on wheels" lifestyle.
One thing the 210P does not have is an exterior 120VAC receptacle. This may not be a problem if the site one rents has a meter with both 30A RV power connector and 120VAC ground fault receptacle. In such a case, all that is required is an outdoor rated extension cord and we can power up lighting, an induction heat plate or even a boom box. However, if the campsite has only a 30A RV power receptacle then we face a dilemma. The only way to get power to an exterior device or extension cord is to leave a door open and use one of the ground fault protected 120VAC receptacles.
That solution was not acceptable to me, and so I decided to add an exterior 120VAC receptacle. The following video shows how this was done without violating the integrity of the RT body and fiberglass shell.
