I've had a new vent/fan waiting to install. But I don't want to spend a couple hours on the roof removing and cleaning the old one. There's 15 years of lap sealant on the old one. I might find fossils.
Some things on my trailer just couldn't wait. In July I replaced the front wall. This time last year, I started the install of my PV/LiFePO4 upgrade. Since Covid had so much shut down, I didn't have much else to do. I also rebuilt the ceiling and interior wall of my bathroom last year. It was one of those things that I said I would get to when I had time. Well, I had plenty of time. Git 'er done!
