Thanks for the information and links! We camp a lot at beaches so sun is "usually" pretty good. Im not overly concerned about the microwave honestly but a medium sized fan would be most excellent. I was told by the person selling the camper that the 6v batteries are the way to go. If getting 3 12v is better I would like to hear about it. I thought duration and charging would be better as well? would all batteries charge when using the panels? There is a kit w/o the inverter if that would work as well there are smaller 100w system as well but I thought 200 would be about right.
