Dad put a penguin AC Unit on his pop up camper. It would keep you very cool in hot weather.
I will definitely look into that.
This one, while it works is very marginal. Right now, the coach interior is 69,
the discharge is 59, and ambient is 85.
that is only 10°F differential.
We have to be very cautious to keep the door closed, and if opened, shut it fast.
it appears that is also a Dometic product, and available in 13,500 and 15,500 BTU
but at $600 average cost, it will be a while before I splurge on that, most likely as long as this one continues to work.
