106f here in Longview, Wa. The A/C standard is the Dometic Penguin II, 15,000 btu heat pump. They also make the Brisk Aire, might be a bit better unit as it is newer, but the Brisk Aire will add about 3" to your overall coach height (might make the difference between a 'close one' and an OWW!). Coleman, and other brands I know nothing about.
