Although if something happens with the main AC, 9200 won't do the job.

Thanks again,

Fayne -

On my Alpine, the rear A/C is a 15,000 BTU A/C heat pump and the bedroom is a 13,500 A/C only. Both are ducted into the ceiling ducts. However, the bedroom A/C can also be opened to flood the bedroom with cool air . . . directly straight down on the bed! Actually, the Chihuahuas love that! When running, I can tell that the front A/C is using around 10 to 12 amps, and the rear A/C is using around 15 amps . . . when running. Add about 5 amps on start up.

I would also like to suggest that you consider a dehumidifier. We have an EvaDry-2000. It does a very nice job of pulling humidity out of the air inside the Alpine. That will help reduce the condensation from the A/C units that drips down the front and back.
