Did you ever find the carport? You could park the trailer inside and have extra shade.
Also, if you own this trailer you could make some plywood walls that block the dust that'll blow at you from underneath, so when you sit in front of it the dust and wind doesn't constantly blow all over your sitting area. I saw some of these low plywood walls painted up with some interesting art. Mushrooms and weeds and stuff.
The heat makes my arthritis feel better so I don't bother with a/c. Maybe a FIGJAM swamp cooler someday, but for now I'm okay roasting (a little bit) if I gotta.
I'm the MAN in a truck, burner who is stuck, you're in luck! I'll whip out my BIG tow chain and not charge you, not even one lousy buck!
