We went in with our Airstream which has low clearance and found a night spot on the right side of the road just before the sign. That was as far back as I was willing to go as the road got rougher near the sign.
I got my 35ft Fifth wheel in with my non-four-wheel-drive 3/4 ton pickup, but be advised the roads are rough and there's some dips/humps that a low-clearance vehicle might not be able to traverse.
