Now that I have this I'm going to figure out how to put solar panels on it . I'm thinking 2 400 acp hour battery's with enough panels to keep them topped off. Propane can run the fridge,furnace and water heater. Looking for LED lights for the inside and going to run wires for USB ports. Biggest power drain is the furnace fan when used for winter camping. My goal is to have the ultimate BOV. Any suggestions on this? Thanks.
