Window Plan

I’ve decided the Scenario Mobile should sport a row of four smallish windows on each side centered above the rear wheels, resembling portholes on a jet or submarine. Remember the Proteus sub from the 1966 sci-fi classic, Fantastic Voyage?

They will be 14-inch squares with 2.5-inch radius corners to mimic app icons in the iOS dock on iPhones and iPads. I’ll even label them with “app” title decals that reflect my professional services.

I can’t find any pre-fab windows meeting these specs, so they’ll need to be custom made by Motion Windows. They’re in Vancouver, WA so I can pick them up and save on shipping charges.

Here’s the hole-cutting template I worked out. This is based on a nine-inch grid to nestle each window between the two-inch frame ribs, which are spaced about 18 inches apart on center.

I’ll cut the corners with a five-inch hole saw, and then cut the sides with a DeWalt jig-saw and/or angle grinder. There will be no room for error. The windows will clamp in place, made watertight with gaskets on the outside and inside.

The critical dimension here is my finished wall depth. So that means before I can order them I need to remove a few interior panels to expose the ribs, and then decide on how thick my wall sandwiches will be, including the insulation. I’m guessing that depth will be around two inches.

I was quoted a cost of $248 per window, or $1,984 total and a lead time of six weeks. That may seem excessive considering larger off-the-shelf RV windows can be had for under $100. But these portholes would be the most distinguishing exterior features and make for a truly unique design element, completing the theme.

To keep the design clean, I don’t plan for these eight windows to open. I’ll add vents on the ceiling, and larger stock RV windows on the back doors and behind the entry door later.
