Quick update for us as well.
I put a Vortex fan in the bathroom. Easy to install and moves a ton more air. I read that someone put louvers in the bathroom door so they could run the fan with the door closed. I'm going to try that.
Fixed a wonky black tank issue. Long story short, the PO had the tank removed at some point and when it was reinstalled they didn't thread the toilet piping back into the black tank correctly. After a fun job, it's all cleaned up and no mystery odors.
Installed a memory foam mattress from Amazon. Way, way more comfortable.
Installed Hellwig sways front and rear. This is a no brainer. If you're on the fence, do it. Seriously, do it. There is no longer any sway from passing trucks. Crosswinds have minimal effect. Even when parked there's an improvement when people are coming in and out or moving around. Highly recommended. These plus the Bilsteins completely changed my family's attitudes towards riding in a big vehicle.
Ordered all new glazing for the windows from pellandent.com. This job sucked, but it looks way better now and I'm sure things are sealed up tighter.
Added a U27-12XP Valence Lithium Battery 12V 138A house battery I got from a buddy for cheap. Still working on solar solutions but we haven't gotten close to running it down yet. We still do generator for microwave, haven't needed the AC yet.
We've taken it out 5 times now and it's functioned flawlessly every time. For what I have in it, it's perfect.
