Like all above mentioned the roads are just fine. When you get to the gate you can check on the construction areas to avoid. The side roads that restrict large vehicles are well marked. That said. If you really want to enjoy Yellowstone and have access to many of the areas with very small turnouts, try leaving the rig in West Yellowstone and renting a car from Big Sky Rentals just across from the Yellowstone museum. We rented a van for our two rig party and had a blast. They also have an attached mechanic shop which saved my vacation when the a/c compressor gave out on the Adventurer. Nice people. Back to your trip, the street in that area is exceptionally wide, there is a dirt lot next door that we parked the rig in waiting for service. I would think you could just leave it there for the day and rent a car and have a lot more fun touring. JMHO, Happy Trails.
