Yes.
And the answer below is correct. When we were there, at that time, I thought we were in the wrong place, but we were in the right place. There are no actual sites.
Big 5th wheel: Go in, turn right, go mostly around the circle till your tow vehicle is pointed back out, and the perimeter is sort of a corner behind you where you can back your 5th wheel up to the fence. Plenty of room for you.
Also, if you need water, as you go in, turn R and begin around the circle, past the restroom, maybe 75 or 100 feet, there is a water spigot that works that is attached to a telephone pole when we were there.
