Serg, the Mid-hills campground is up a rough dirt road, and the campsites are smallish and not level. When I drove up to it I told myself that I could get my 23' up there if necessary, like if the other campground was full, but it would not be preferred. A bigger trailer would not be recommended. I was in my F150 at the time.

But just a few miles south is Hole-in-the-wall campground which is a very nice RV spot with level sites, water, and a dump station. You could easily camp there and join the other group for touring around.

BTW, I would choose to enter from the I-40 side, not the I-15 side. But that's just my opinion.
