Discovered on our last trip that the overhead cabinet doors have screws that go all the way through. The way they were discovered was we decided to roll a days worth of clothes up and stuff a weeks worth in the overheads so we could just pull out everything to get dressed in the morning. I think the first day my shirt got snagged on a screw. Got through the rest of the week with no more rips by being extra careful. The idea worked well accept for the exposed sharp pointed obstacles. So now I have thin strips of wood above each cabinet to use up the extra screw length. Can't imagine why I never noticed the screws before.
Second project was a dripping Shurflow faucet when running. Didn't look repairable so was planning to replace. In doing a search online I found that Shurflow has a online chat service for repairs. After I posted the model number and that it was leaking at one of the joints and wondered if it was repairable, they asked a bunch of dumb questions like when did I service the hoses and what RV I had, I finally got forwarded to someone to answer my question as soon as I gave them my credit card number, I left. Found a comment in one of the reviews of the product that there was an o-ring in the joint that was leaking that you could get to by pulling harder. Figured worse case it would break and I would have to replace it. Came apart and I found replacement o-rings at Lowe's 10 for $2.50 that with a little silicon grease fixed the drip. Maybe just the grease would have fixed it.
The rest of my B projects for now are longer term but I hope to get to before our next long trip but are only niceties, not priorities.
