71. Air Conditioner field tests

We did some operational tests of the removable air conditioning doors at Palo Duro Canyon where the afternoon temperature was in the upper 90's. It took me 4 minutes to change doors and install the air conditioner. Joe did his in TWO minutes. (But he's had practice, and he used good tools.)

It appears that our system works really well. We built a flange onto the air conditioner with aluminum angle channel, and simply bolt the assembly into the door opening. I was worried that the AC weight might cause the door to sag, but that's not the case. The torpedo hinges are quite strong. Joe says he wouldn't be afraid to pull the trailer nor to open and close the door normally with the AC installed. He went ahead and installed an exterior door latch on his. I believe he is right.

The 5000 btu AC unit cools the trailer down to walk-in beer cooler temperature in about 15 minutes. I pulled up the covers and slept good in mine.
