WHere I was camped last week the heat index was higher than the shore power line voltage.. And trust me, HAD I moved the motor home in that heat the generator WOULD be running for the roof top A/C's This week... Well,, I opened the door and turned on the fans as the A/C was not needed (parked still and not all that far away) NICE!!!!

Home is where I park it!

In some cases far more than a residential system.

Bear in mind, when you compare an automobile to a S & B's, the residence;

- doesn't have an engine pumping out heat next to it,

- has adequate insulation and thermopane windows, usually coated with low-e and filled with Argon,

- doesn't have a ratio of glass to opaque of 30%, a typical S & B has about 5%,

- isn't allowed to get to triple digit temps before the AC gets turned on, and then the system is supposed to drop the interior 30+ degrees in minutes.

As some examples I found, (in BTU's) a Honda Civic has a 12k system, a typical minivan has a 24k system, an Acura MDX has a 19k system, a VW Jetta has a 24k system, .
Now if if you're looking at the systems in say a Ford Econoline 12 passenger van or Excursion with the dual (front & rear) AC unit, is it really difficult to imagine that their more than double the capacity of that in a VW Jetta?

Here's a link to the Sanden website, the specs show that even a car system designed for smallish import cars has a compressor that's well over 20k.
