In Jan. of 2008, we were at a resort in Yuma and had an electric bill of $158 (one month). We paid .18/kilowatt. Never came close to that before or after at any other resort. We spend most of our winters in Florida and the resorts there can only charge the camper what the power company charges the resort. Apparently not so in Arizona. We do have an electric fireplace which we use a lot, especially in Arizona where the evenings are cold.
