While installing a 2nd TS-30 between the current one and electrical panel so I can run the fridge and outlets on an inverter, I noticed that Thor uses twist-on caps for their electrical connections, which is a no-no IMHO.

Why, because RV manufactures often join dissimilar wiring, which is what they did with mine, so crimp-on and/or soldered connectors are required.

Sure enough, one of the 3 neutral wires EASILY fell out of its twist-on cap when I was verifying tightness on the caps Thor used. It VERY tricky to ensure a tight, vibration-proof connecting household type hard wiring to 12-volt soft wiring, which is why I use heat shrink solder connections on all of my mobile projects...

I also noticed a bunch of wood-structural issues, but these things are pieces of crap, so it is what it is.

Again, this could have caused a fire. Check everything in these things. I already advised you guys weeks ago about Thor stapling through my bathroom wall and into my PEX tubing.

This is a known Thor issue. Some have found this problem when they smelled burning plastic and found melted twist-on connectors. Always the first place to check with 120 VAC supply issues.
