Thinking back on original question, I live in very hot and humid southeast Texas and my AC at home can cool house to 75 F when it's 105 F outside. And my son's new home which is insulated much better and has an AC that is too large can do even better. The system just has to have enough cooling capacity to meet or exceed the actual load at whatever conditions one wants to operate.

Chance,
I whole heartily agree. For me the majority of the threads provide a "take away" or a "lesson learned" and in thread my lesson learned is:
If the temperature split or Delta T is 15 - 20 degrees the coach will eventually cool down. The amount of time required for cool down is dependent upon how well the coach is insulated, the outside temperature, the outside humidity, and most importantly, the number of times someone opens and closes the door during the cooling cycle (especially if the cool air return is located close to the door).
