This is the third or fourth eighth iteration of the electrical plan, but the first version to be fully digital. I’m using a Progressive Dynamics PD4045 power distribution panel to serve these circuits. This is the go-to panel in the build-it-yourself travel trailer world. I am not thrilled with the location, but hard pressed to think of a better one. It needs to go inside the interior, and I don’t want it under the sink where water may get to it. Ditto for over the shower.

Horizontal chases are shown. I believe there are vertical chases, but I don’t know where they are. If not, there is a method of creating one on site using a hot ball bearing.
