Are you stationary or do you move around? Four batteries + solar panels can get somewhat heavy and eat into your total capacity, so I'm curious if it's an issue.
We are very mobile, usually stay in one place for a week at a time and then move a couple hours away. You're right about weight though, we are right at our GVWR (11,000 pounds) when fully loaded. The batteries weigh 100 pounds each and the panels are another 15 pounds or so each. That said though, we get terrible gas mileage already so the extra 500 pounds for everything doesn't change it much.
