Well the paint on those window covers is definitely did not adhere well. But it won't be a big deal to take it off at some point and do it again proper. Lesson learned.
Here's a quick update on the progress. We moved the bus closer to the barn / small woodshop and started using grid power when we painted. The solar set up works great and will run a sander and a grinder all day but not, I assumed, a 1 1/2 hp compressor.
I made the tank hangers. There's a 40g. fresh tank on each side and two 40g. grey tanks on one side. The hangers are made of 1/8" thick 1 1/4 x 1 1/4" angle. They're bolted together and through the floor except for the bottom members and the diagonal braces which are welded. The bolts through the floor go up through the floor joist (don't know the vocabulary) channels.
I wanted to know how difficult it would be to get a motorcycle inside so I made a janky temporary ramp. Not very convenient but it can be done without altering the layout much. This bike is unusually short.
The roof hatches are cracked and in bad shape all around and just seem like a crappy design to start out with. after having a hard time stopping the leaks i got fed up. It felt like a nasty thing to do on our nicely painted roof but it works and I can always goop some more on in the future.
For the floor I made some 1 1/2" x 7/8" furring strips and glued and screwed them crossways to the floor. Each one sits on top of one of the support channels under the steel floor. The spacing ended up being 18" O.C. and the space is filled with 1/2" rigid insulation. I put down 1/4" spacers before the insulation to give a little air gap. Everything got taped up nicely and covered with the t&g flooring I'd made earlier.
Now I'll do some finishing touches on the floor and install the solar panel mounts before covering the ceiling.
