How fast does camper cool with A/C?
I just bought an 8000 btu portable. Initial run for a few minutes it seems to work well. I havent vented it yet, will need to fabricate opening.I cant justify spending close to a grand for a roof mode...

Hi,
It really depends on how large the camper is, and if you have slide outs. A normal camper with 8' long floor and say 3' tall cabover that is 5'X8' then you have about 64 square feet at 8' tall, along with 40 square feet at 3' tall. So a total of around 750 - 800 cubic feet.
A 2 ton (24,000 Btu) home air conditioner can cool 800 - 1,000 square feet while moving 800 cubic feet of air per minute! So 24,000 Btu's will cycle all the air in your your size camper every minute! But your A/C is only 8,000 Btu's so it will actually take 4 minutes to cycle all the air through it.
My guess is that unit will be large enough. That said, you have a portable A/C, so it will be taking cool air from the RV and through the condenser, then out the exhaust tube, so it will take a while to make up for the incoming outside air that is being blown out the air conditioner.
I would HOPE that you have a two tube portable air conditioner. This brings in warm outside air, then heats it even more, and then only blows out that hot outside air, not blowing the cold inside air out the condenser and hot air tube.
You might also want to consider making either a window vent, or perhaps a roof top vent adapter to blow the heat out and take in outside air when you need it.
