We are a fam of five, plus two dogs and camp all around the Houston-Austin-Dallas, TX areas. I.e. it is HOT in the summer.
The single AC unit suffices during evening/nights IMO, set to ~75F it does not run continuously ... it can feel stiffy if everyone is indoors during the hottest time of day (12-3 p.m.-ish), but why would you be indoors if it is sunny out - lol.
The unit is wired for a second AC above the master, however we have not seen the need for it.
As far as other PROs/CON's are concerned, there are no major negatives - hence our choosing of this model. There are ample mods that one can do as you can read on this forum, most are the result of personal preferences and general camping gadgets to help.
A light by the power/sewer hookup would be beneficial if hooking up at night, i.e. bring a camping lantern.
The outdoor kitchen is great, removing the grill for storage is a bit of extra work as it cannot stay attached for travel.
Overall we prefer this make/model over MANY other units we have reviewed over the years.
