WHAT RV AC DO I NEED IN WARM LOCATIONS?

If you are travelling to cooler climates then this will not challenge the air conditioners to the extremes, a unit with a smaller power rating will do for these types of trips. You should not save on power, though, if you regularly travel to warmer climates and even less so if you have children or pets on board as staying in a recreational vehicle can quickly become uncomfortable on a hot summer day. When the nights are not cooler either, rest and recuperation is only possible with an adequate air conditioner.
