I've lived in Florida my entire life, camping for 35 years. The inside of my camper is usually higher than the outside temp once we stop. Here is what works for me: Travel with the vents open whenever possible (vent covers with lots of ventilation area!) As soon as we stop, I open the doors, windows and vents to let the heat out. Fire up the A/C and a fan if you have one and let it push out the heat while you finish setting up. Once set up, close everything back and let the A/C work. Sit on front of a fan with a cold drink until you cool down from all that hard work!
