I read the same article. My guess is that the new owner will double the space rent and hope that the tenants will vacate voluntarily. I'm also guessing that he actually wants the land for a hotel or condos.
We stayed at the Islander RV park for a couple of months this winter and the price for a waterfront view site was $675 a month plus electric.
We ended up getting a really good deal on a home on a large lot with a great view of the lake and mountains for the same amount per month as the RV space.
It was an easy decision to have a home for the same price as what we were paying for a 40' x 60' RV site.
