Yosemite and RV Height Restrictions

[ThorOutTheDoor]

We're headed to Yosemite later this year and I'm concerned about our RV height. Our ACE is 12' 2" tall and I hear that it won't fit through some tunnels in and around the park. We will be coming in from the west, probably HW 120. Went to the nps.gov page and it show height restrictions for some tunnels but i'm not familiar with the area or the road names and locations. Also, it seems to matter if we're entering or exiting the park, so I'm confused. Anyone know of a source that has a good description of what to be aware of? Thanks!
