The first task was to climb up on the bus roof to reseal one of the seams. That took a complete cylinder of silicone sealant. Ideally I'd have used something other than silicone but since I've used silicone everywhere else and it seems to be working, I've stuck with silicone. This motorhome will only ever be a 20 year old vehicle. It will never get younger so imperfections aren't that important.
After that, I thought about my plumbing. I decided that for the moment I'll plumb for a bucket under the bus. It should be straightforward to add underbody tanks. The plumbing didn't go quite as planned as it was the last thing done today. Needless to say, I cut the tubing too short after having previously cut it too long. It's currently an inch too short after being an inch too long. Having said that, this is what it looks like.
Another task completed was to weld the two parts of the roller shutter top that I'd previously cut into two pieces. I welded with 6011 rods both at the top and the bottom of the join. I did several runs with the welding rods in order to make the welds look good. In between runs, I wire brushed the slag off the welds.
I have concerns over whether my underbody work will be too much for the skeleton. I might complete what I'm building for the underneath and then ask my mechanic for advice and maybe get him to weld the underbody stuff. I really don't want stuff dropping off as I'm driving!
