Still working on electrical when I can find time. Fishing wire through the conduit for the raised deck, and getting everything ready to seal the deck is challenging.
I made this wire whip with mesh cover because this is the wiring that will go outside and through the trailer tongue to the trailer connector.

This wire runs down the center 2x2 tube and exits near the front of the trailer.

The wiring enters the trailer into the raised deck through the stainless steel wire flange. I trimmed a bit of the plywood down, as I'll be permanently sealing this port with epoxy.

A washer was added to the flange so that I'd have a way to secure it to the deck. I used a circular template and filled it with epoxy just over the rim of the washer, and it sealed the wiring exit from the top.

Some leftover blue conduit was used to help protect the wire as it goes through the opening of the 2x2 framing.

Here is all the wiring mess converging on the mid-section of the raised deck.

Somewhat cleaned up, you can see that the marker light and trailer brake wiring go through the conduit to the outside edges. The top conduit has the radio remote wiring and speaker wires for Galley speakers. The middle blue conduit has power for 12V receptacle, USB outlet, and return wiring for the galley light switch. The bottom conduit has the wiring for the 110V outlet. Holes will be cut into the top deck to allow these wires to pass through, but this will be within the space of the front cabinet, so hidden.
