I drive my Camper with the AC on almost year round in Florida and find it
more than adequate. I usually run the fan at "3" and the temperature set
midrange. It takes careful aiming of the rear vents and sealing all of the
fresh air openings on the dash and roof. A white roof and limo-tinted
windows also keep the heat out of the van. Finding shady parking spots helps
too.
As for the power, it will still do 75-80 mph with the air on, which is
faster than I normally travel.
