We chose the larger capacity model (I'm pretty sure it's a Dometic) since we have the built in Onan to power it. It does get warm inside anywhere you have a skylight (in our case just the bathroom), so we wanted sufficient capacity to handle triple digits. Even if we don't stay in places that get that hot, we do travel through places that stay that warm and wanted a system that could keep up with the heat load and normalize temperatures quicker. In the Summer of 2015, we visited southern UT where temperatures peaked over a 100 degrees every day and our Arctic Fox handled interior and fridge temperatures just fine - I would not want to skimp on AC if you plan any desert trips. Our Arctic Fox had two skylights and the bathroom could have been converted to a sauna when you left the door closed. We would hang our towels in there and it felt like they were on heated drying racks even with the vent open.

Thanks Bedlam. I have been studying the pictures you posted of your roof trying to figure out solar panels. Your AC looks to be a coleman mach. So that answered one question. The coleman is the 11k unit and the dometic must be the 9 k unit. I was hoping to find the specs concerning amp draw and efficiency rating between the units. They advertise that the small one can be used with a 2k generator inferring it has less power draw (and possible a softer start) which makes sense but that doesn't mean the efficiency is better. Sometime a larger higher efficiency unit will use less (or not much more) power as the compressor will cycle less.
