Another option is to install solar power. Wow, isn't that a big expense? Depends on how you use your RV. If you do have solar, simply park your rig where the sun shines, if you have a good, reliable inverter/charger and batteries in good shape (they will last many years in a good setup). If you ever wish to dry camp/ boon dock, or whatever you might call it, you're already ahead of the game. Anyone near will appreciate the sublime quiet emanating from your RV. too. I am constantly wondering why expensive rolling homes are without simple solar.
