On the last trip we started off by finding the windshields were popping out at our first stop, as in about 1" off of the body. We figured at that point we needed to just turn around and come home, but after calling a local RV repair shop (local to our house) that had a very good reputation, they said they'd just put Gorilla tape on the windows and finish up the trip, then fix it when we got home. So that's what we did, and it worked out. On that same trip a propane smell that was occasional got more significant, and so we had them take a look at that.
Just picked the RV back up from the shop with the windshields reseated and the propane leak fixed - sure enough it was a fitting that was coming loose in a hard-to-find location and needed to be resealed. Good parts being that no appliances needed to be replaced and it was in a hard enough to find location that I don't feel badly about paying someone else to fix it for me.
The next project we have on this isn't going to be fun. Well, projects. The easier one is that I need to change out the oil pump on the engine, or at least I have low oil pressure and I have come to believe that's why. I changed the sensor out before the last trip and there was no change in indicated pressure. So I got a new pump from CAT and need to drop the oil pan. There's nothing in the way so it's just draining the 5 gallons of oil (time for an oil change anyway) and remove the 35 or so bolts holding the oil pan up, then knock it away from the engine (I'm sure it won't come too willingly). While the pan's off I'll weld in a bung for an oil temp sensor (something I feel like this engine should have, but doesn't). All in all not too terrible of a job, but something that needs to be done. And if that doesn't solve the issue, at least then I'll know if the issue is temperature related with my new sensor, and can then keep diagnosing. These engines are known for low oil pressure and the oil pumps do often have issues, so not surprising. It's technically above the limits but definitely below where it should be.
The more annoying project is going to be replacing some amount of the flooring and subfloor. We did see a couple of cracked tiles when we bought the RV, but nothing indicated a soft floor. We figured some shifting after 20 years. Turns out the subfloor in one area was rotted enough that one of the tiles ended up going through. We didn't like the tile anyway but also didn't want to redo the floor, so we were just going to live with it. Now we'll be tearing up some portion of it and then replacing.
Apparently even though Holiday Rambler is supposedly a good brand, they made the flooring with particle board which is particularly prone to getting soft over time with any water exposure. This is a relatively common problem and people replace the subfloor with an exterior plywood that will hold up longer than anyone is likely to own the RV. So, time to start tearing that up...
