We had
Cabin Fever up to Gunnsion Colorado last weekend in a campsite with shore power, so I tried the air conditioner out. It blew cool real well with one hose

and after an hour or more still hadn't frozen up, so I think that's how we'll use it: pulling warm air from outside in. I left the roof vent open, and the cabin cooled well enough for me to take a nap, while Shelly slaved in the galley. The AC pulled a lot of water from the air, judging by the discharge.
The controls in the cabin didn't work however, so this morning I took everything out of the utility compartment, took the top shelf off, and pulled the AC unit out and up to the workshop for repairs. (I have power in the workshop, not in the garage where the tear is stored.) We had installed the AC before putting on the doors, so that was a slight issue. This is one reason many techs and field engineers hate design engineers, and one reason design engineers ABSOLUTELY should go out on field tests with any new prototype they designed (campers, aircraft, communications systems, anything!) (Well, okay, unmanned spacecraft and unmanned high altitude balloons maybe not so much. But I'm getting off subject.)
The cargo doors had a very deep lip, which is probably there for rigidity. I should have drilled some neat holes during door installation, to get to the screws holding the AC in place, but today I had to settle for some less neat ones

Oh well! They're only seen when opening the door to the utility room--sort of akin to a basement in a house.
Once I got the AC out and up to the shop the problem was immediately obvious (thank goodness). The connector Climateright used was flaky. I could move it around and make the wired remote do strange things. So I replaced that connector with 4 gold plated bullet connectors, color coded so even the silliest idiot (read: my future self someday, trying to fix this in bad weather) will get it right.

We'll be testing it out in a few days in the mid-west, so I'm glad I put the time in, even though it took a long morning!
The tear itself has now been tested in rain (both while stationary and being driven) and passed with flying colors. We are pleased.
