I know my coach is a power hog - it draws a steady 1 amp even with everything off. When we are living normally in it, in moderately warm weather, we use 18-24 KWH per day. With a/c usage in the afternoons, that doubles easily. So $3 per day for power is not at all out of line for us. More like $6 with the a/c's running very much.
What does a KWH of power cost in theTucson area?
