Weekend Update: We've made some progress, and things are getting really exciting! The rough framing of the kitchen is finished, including the uppers. The water tank and the AGM battery were delivered. Here's the layout we're going with: The two burner stove will be at the center of the V, and the sink will be on the left by the tall cabinet. The tall cabinet will hold the porta-potty behind a door at the bottom. The refrigerator will be in an open space above that, and at the top will be a storage cabinet.

We put shiplap up on the walls. It was pretty easy, and VERY affordable. We used 1/4" plywood, and ripped it into 6" wide strips. Then we did a paint/stain treatment to give it the gray, weathered wood effect. To do that we painted the strips white, then sanded it down to leave some white and some bare. Then, we went over that with gray stain. Once the stain was wiped off, we were left with a look we're very happy with.

Then we got busy on a valance to cover the torsion mechanism for the ramp door. We wanted it to be removable for future maintenance, so we screwed in a 1/2" u-shaped aluminum molding. The bottom horizontal piece slips into that channel, and then there's a screw on each side holding it in. So if we need to remove it in the future to adjust the door or whatnot, we'll just remove the two screws and slip it right out of the channel. Seems to work so far.

The AC unit was finally delivered, and it fits in our opening. What a relief!!
So, we're pretty happy with how things are moving along. We made another run to the home improvement store today. That's a 90 minute drive each way for us, so we tend to hit it pretty hard and stock up on supplies for the next 1-2 weeks. So, we've got plenty to keep us busy. I'll keep posting as things happen.
Have a good night, everyone!
