@SteveJohnson You can start the solar panel habit slowly. I've seen small set-ups available at many stores at a reasonable enough price. Mine came from Harbor Freight. The panels offered now are 100W and comes with everything you need to get started, except storage battery which your RV probably has/had. Any amount of time you don't have to run that generator is good for the environment. Oh, price on those solar panels is about that of 60 gallons of fuel in Indiana.
