Never stayed at this park just outside of Niles, MI, but have driven passed it. Not a bad looking place. FHUs and reasonable rates (under $200 for the week).

http://koa.com/campgrounds/covert/This next park is just east of South Haven, MI. We've been by it several times while staying at the local state park. They are a bit pricy, but it's a new and expanding park.
