Length restricted rv parks

I have run into a few length limited parks.. For example the vendor operated RV park inside the Grand Canyon National Park is length limited. So I drive through it.. WITH MY CAR and .. Well.. Yes.. I'd not wish to try to take my 38' Class A into that place. the turns are too tight.. I have been in some state parks like that as well back in my PUP days even with the PUP one of them was tight.

So now you know. it is not "Discrimination" it is turning radius.
