I like this idea. While not to crazy about having AC when camping. Grew up
without it and just now having it for bed rooms in the house. It does make
life easier with young ones as they don't wake up in the middle of the night
from the heat. Also a floor mount would allow you to use a non-RV roof AC
unit. Some of the window units are cheap and could be converted to work on
the floor. Now finding a good floor space is the trick.
