We do not allow tent camping of any kind, including rooftop tents. Our hosts have signed on to our program with the expectation they'll only receive stay requests from travelers in fully self-contained RVs.
Here are some alternative options that may work better for you:
Tentrr: https://www.tentrr.com/:
Connecting adventurers with private landowners who want to share their land.
Campground Views: https://www.campgroundviews.com/
Campgrounds that allow both tents and RV's to stay.
