Thanks again, Jayco. I think we're gonna wait until we burn through some of this gas to tackle that issue.
So everything seems to be working quite well, so far. We steam cleaned the carpet, couches, bed and curtains. We went through and did a deep clean vacuuming all of the nooks and crannies we could get to. I pulled the "dog house" engine cover and stripped it down. The fiberglass insulation was halfway missing. I bought a water heater blanket and some insulation tape and went to town. It turned out quite nice and now I can drive the beast barefoot and barely feel any heat coming from the motor. After the oil change it's running nice around 45 psi at operating temperature. I'll probably drain and replace the coolant, but it stays well within the operating temperature now.
We're out for our first week in it to test drive all the appliances. The fridge is cooling down quite nicely on 120V (I also tested it on propane and it seemed to function well) The little old oven fired up and all three burners work great. The propane heater fired up and cooked us at 450 degrees in about 2 minutes.
The only problem I found was here:
I believe this is the water line for the old swamp cooler on the roof (Does not work) It looks like it was plumbed right in to the copper tubing. Well I followed that plastic line and it looks like it was cut and somebody tried to plug it with a screw and electrical tape.
It leaked quite a bit, so I had to shut off the water. I'm guessing I can just unscrew that fitting and sweat in a joint? That swamp cooler isn't going to work any time soon and we're just gonna save up for an A/C unit to be installed later. What do you guys think?
Other than that it's been pretty smooth sailing. I'm amazed at how well this thing runs for being 40 years old. It's a great machine.
