Personally I see two choices. One, figure out how to live, work, travel year round, homeschooling is a viable education option. Lots of people do it successfully.
Two, sell everything, downsize to a reasonable sized house, get totally out of debt, save as much as possible and plan to retire early.
Remember your house and property are appreciating assets, RVs are not. So every dollar you have in real estate can potientially return several dollars down the road. Every dollar you spend on an RV will be worth next to nothing in ten years.
