I've been fulltiming since '06 on a partial military retirement (ex wife got about 30% of it) so I still need to work. There are places other than campgrounds to work and make decent money, especially with both of you working. I've worked the Christmas rush at an Amazon fulfillment center for $10+/hr plus they picked up the campground fees. I've worked the sugar beet harvest in northern MN for $14+/hr. With your accountant background you could travel the country working at tax centers while your DW worked a campground office to pay for the site.
If you'd rather keep doing the accounting work remotely, create a small business now and start getting your clients before you hit the road.
