I spend a lot of time traveling the country to some of my favorite places in my Pleasure Way RV, often these places are warm, like Lake Havasu, Arizona. With two Golden Retrievers, keeping them cool is obviously critical.
My RV does well with the installed Fantastic Fan, and the draw is minimal. Regardless of what I've done on the batteries - often watching a movie in the morning or the draw of the fridge, my portable solar panels ensure that the batteries are charged and the dogs are cool. While an air conditioner is to high of a draw for solar, everything else runs great.
