It's done!
I had the recycled rubber floor installed. I painted the floor tracks matt black and reinstalled them on top of the 1/8" rubber. I have black caps for the stainless screws and bolts but I may leave the heads exposed.
The cabinetry at the front of the bay is finished. The devices near the ceiling are the water tank fill port and sight glass. Each side cabinet is about 24" wide, 20" deep and 30" tall. Each cabinet has a shelf.
It's going on Maiden Voyage 2 tomorrow. Same show, same route, same car in the back. The only difference is, I'm not driving. I'll be about a 1/2 hour behind him.
