The only place you might have a problem is on some of the scenic or historical turnouts. Some of them are marked that RV's should not use them, but even those signs are somewhat small and hard to see. Still lots that took our 70'+ without a problem. One other issue you might watch for is that some sections have tree branches that impinge on the roadway, but there were not enough overhangers to cause us a major problem, just something to watch for. It's a great ride.
