do you take rvers who want full time places and for retired folks, if so what are your monthly rent for extended stays thank you

Good question. Best to call KOA direct.

I would either call directly or ask on their website or app

For best answer call KOA Eureka Direct, they will have all your answers, and yearly membership is required. Points reward system towards all types of rentals,

Each one differs. I would think so.

I agree with Alex. I would call the campground directly.
