We were there 3 yrs ago and the road in from the north was the worst wash board I ever drove on and I used to work for the Forest Service. They said the southern route in was even worse. Aparently the park doesn't do the road maintenance. Just have to go slow and make sure everything is secure inside your RV. Worth the trip and IMHO better thean Mesa Verde , Canyon DeChelley and the others we have visited since it is more pristine, has not been restored and fewer people. When the sun goes down in the Canyon and you are so close to the ruins it is just awesome.
