Completed the installation on Saturday with expert help from friend and fellow Airstreamer Brad Norgaard (FLYFSHR) (see pic below). Even though we both agreed that the location for the new outlet was perfect, I was a bit apprehensive cutting holes by myself but having Brad around calmed my nerves (he did most of the cutting). The hardest part was getting the holes cut just right for the metal outlet box.
This project was made easier by the fact that the storage compartment already had an 120v outlet in it. This oddly placed outlet took up a fair amount of room in an already limited storage area, so this modification was a win-win for me. We simply used the wiring from this old outlet. I'll strip and polish the new outlet when I polish the Airstream later this year.
