It shouldn't rain for a few days and the brackets are fully painted so I have few qualms about just leaving them out to dry. I looked at my previously welded barrel hangers and the paint was protecting most of them well. One had a little rust showing. Perhaps coverage wasn't complete there or it could be the slightly porous nature of Rustoleum showing itself.
Looking around I noticed two strips of steel. Cutting them to exactly 31.5 inches long, they were easy to fasten inside the driver's window. An extra length is needed but that's a trip to Tractor Supply. They also need to be painted before they rust. I'd like to have had the bars closer together but there had to be enough space to put my arm through in order to beckon on motorists or to use toll booths.
Thinking about tomorrow, it could be a good day to put some of the brackets under the bus. It could also be a good day to make plywood panels to fit inside the rear windows. Then of course there's investigating the strange wiring under the bus and identifying the strange object connected to the drive shaft. If it's an external speedometer, it's probably worth removing and fixing the original speedometer sensor in the transmission unit.
I'll have to get some wire in order to get the backup horn working and I'll have to mount the battery for the ventilation system under the bus. There are lots of little projects to be done. The major projects are now all underneath the bus. I'll be so glad to get that done as my knees really are complaining when I get up and down.
