I didn't have time to build the manometer yesterday. I'm trying to make a pad for the van, hopefully I'll be done in a few days. You can see from the pictures that it's just grass right now.
What's the thermostat set to? If it's at max, it seems rather high. :(
Yeah it's on max, that's good to know.

I think I'm just going to run the fridge off an inverter while I'm driving instead of buying a new heating element. Installed a new converter yesterday, should have time to check the gas pressure today.

Completed the gravel parking spot today also.

I finally built up the manometer and it looks like my pressure regulator is bad, only 9 in, should be 11 in. Another problem I found is that if I leave the gas stove on and connected to the manometer and turn off the shutoff valve at the tank and release some pressure with another stove burner to say 5 inches it will climb slowly back up to 9 in so I think the main shutoff valve is bad also. I want to check at the back of the fridge but I will need to get an adapter because the outlet is too big for my 1/2 hose.

EDIT:
I did some more research and it looks like the regulator on the stove should limit it to 10 inches so I really need to check at the test port on the back of the fridge to make sure it's right.

Also, I watched this youtube video and it helped to confirm that my shutoff valve is probably leaking.

Finally found an adapter for the manometer hose. Couldn't find one locally so I ordered one from Amazon. One tip with the DIY manometer, add enough water so that the water does not pass the halfway point on the bottom of the loop or you'll get a fountain of water plus escaping gas. The Dometic 2301 refrigerator has a 1/4" NPT pressure test port.

Before I adjusted the regulator the pressure was 10.5" water column with nothing but the fridge on. After the adjustment, it was 12.1" w.c. with only the fridge on. If I turn on the furnace, the back two stove burners and the fridge, the pressure is about 11.1 w.c. You can actually see a visual difference, the stove flame is about 3 times larger now with no yellow flames.

While replacing the AC capacitors, I found that water is pooling up around the AC unit due to the fiberglass sagging over time, at least that's what I think it is.

One of the previous owners had filled in the perimeter of the AC unit with spray foam insulation. I guess he didn't know the drains were there so he plugged up both of the drains on either side. I had to take a metal wire to pull the insulation out of the tubes, took me about an hour.

Yours has drains? Do they drain underneath somewhere?

The Airstream trailers have drains, but I didn't know any B190s did. My A/C condensate just runs down the side.

No, they just come out of the AC unit onto the roof. I had to clear the foam from the AC unit drain outlet.

Gotcha, thanks.
