Portable A/C
Has anyone used a portable A/C unit in their coach when the built in unit has failed? It seems that in an older MH it would be much cheaper than replacing a basement unit. Cork

Bet you $10 you are incorrect. Roof ACs do not pull outside air into the coach. They pull interior air across the cold evaporator and put it back into the interior. Outside, it pulls pulls air across the hot condensor to remove heat.
You ARE correct that a single hose portable ac will pull air into the coach somewhere.
that is exactly what I tried to say, perhaps ineffectively. yes roof ACS do not pull air into the coach, they pull it into the air/heat exchange area of the unit.
