I was a little stumped by the mounting strategy of the settees in the rear for a bit. Something was missing, as there was nothing to prevent the back edge from raising up when the benches were cantilevered out in "bed mode". Scrounging through the piles of junk in the parts coach finally revealed a nice piece of aluminum angle, that had 4 holes that coincided with four holes in the parts coach's woodwork. Our main coach has apparently not had these installed since its last remodel. I'll probably have to redo all that stuff later, but I can make it work for now.
While dinking around with the furnace install, I made a most unwelcome discovery. Last year I'd installed a GMC propane tank from a 23-footer. It worked fine, and even had a functioning gauge. The fill port didn't line up right though, so it couldn't be filled at most stations. Unfortunately this week, it didn't pass the sniff test. It seems it started leaking at the valve handle stem. I went to the parts coach and grabbed the full-size 26-footer tank that still had propane in it from 20 years ago. Must not leak, right? So I installed it. Then after exercising the valve a couple times, it also started leaking in the same spot. Darn. It didn't have much propane in it, so I had no alternative than to let it bleed off.
I rigged up a pressurizing device so I could put 60 psi in the tank and test it for leakage.
I figure the tanks will probably last about forever, but the valves could likely use a little maintenance.
I pulled the valve apart to find the crustiest o-ring remains I've ever seen. I tried to pick it out with wood and plastic implements, and most of it came out of the gland, but thick deposits were left in the old groove. The bore of the valve was easy enough to polish up using the regular tricks with a wood dowel, drill, tape, and 2000 grit paper. The groove needed a different solution. So I grabbed a soft cotton string and impregnated it thoroughly with rubbing compound, gave it 1-1/4 wraps and see-sawed at it from all angles with the string. I was very, very pleased with the ease of the task and the end results.

A 5/16 x 1/2" o-ring fit the bill, and Ace had individuals on hand. I don't know why o-ring kits never include 3/32" o-rings in this size range. Irritating. Some very thorough leak testing finally revealed that the leak was all gone. The combustible gas detector agreed.
The furniture I collected last year included a new couch/bunk. The seat base was in better condition, but its frame differed from what I had (included a latching mechanism, and slightly different geometry). So I had to sand down another rusty seat frame and paint it up so it wouldn't stain everything we stuffed into the storage space.
I also finished swapping the water tank. There were 7 distinct types of hose involved in the old installation. Yeesh. I rerouted everything and kinda started from scratch. The way the overflow and vent were done was ineffective. While in the area, I found a mystery connector that appears to be factory. It was between the tank and the shower stall. What's it for? The colors are black and green/white. I didn't see anything on the living area diagram that makes sense.
And finally, the forecast called for rain. My seams were nasty and need more work than I have time for. So I scraped off the tall stuff and broke out the Eternabond. That seemed to be mostly effective.
