It's a great scenic route that I've taken several times in my TC. What I've seen taking this route are 5th wheels, TT, MH, and simi-trucks. There are some steep areas, but very manageable.
Hwy14 east just outside of Cedar City
Navajo Lake stop east bound
Duck Creek area, east bound
This sign is at the Hwy89 intersection on Hwy14 going west.
