One thing I have been wondering about cooling since we have no AC and do not plan to hack one into an old scamp
that was not designed for it. Too lazy to re-engineer I guess.
What is the air temp under the camper? Is it cooler than what would come throught the windows
? Could a roof vent fan or a floor mounted fan pull that air in if there was a floor vent?
Those of us who own dogs know that they tend to go to ground under the camper if possible when it's hot. I seem to recall that even the temp under the eaves of a house was cooler than in the house and was the basis for some sort of green cooling system.
Everyone at Amazon gives that cooler fan thing 1 star, for the dog I think I would just put a bucket of ice water down, area of floor near bucket stays cooler and dog can get drink of cold water. 2fer.
