2015 30 foot.. One or Two Air Conditioners?

When the two A/C and 50 amp service option is selected, the smaller (13.5K BTU) unit is typically installed in the rear ceiling vent fan location in place of the fan. This option is frankly a huge profit item for the Airstream option list given the bill of materials at the time of the build out.

That was a $2,129 dollar option for our Classic in 2014.

When the largest AC units available at one time were 13.5k units, folks from 27' up really struggled in full sun hot conditions to keep indoor temps comfortable. When my 30' Classic was built, 13.5k was the standard but 15k units were options. I asked for the 15k heat pump AC Penguin at build time which was a $700 option, and have no regrets with only one unit. Quite honestly if I traveled in the Deep South or southwest I might have considered a rear unit. I've been out in the 90's here in the Midwest and have frond that the 15k unit works well in my 30' slide out.

We never seem to need to use the rear heat pump. I'd question the salesman hard on getting by with 30 amp service with two a/c units? We obviously have 50 amp capability but use a 30 amp cord that comes with a male connector that fits the coach input.

Hi

Consider that humidity counts a *lot* in terms of how hard an AC needs to work. At 90% RH and 90F it is doing a lot of work. Depending on this and that, it likely will be easier to cool from 120F at 10% RH.
