Yosemite Ridge is a good spot. The road is somewhat windy, but is ok for about any size rig. We were there a couple of years ago with a 37" MH, and had no trouble.
Whichever way you decide to come in, either 120 from the west or 120 from the east, is doable. You might want to think twice about 120 from the east, as it is a hard, steep climb, although many do it.
Just take your time and enjoy!!
Happy Trails, Forrest
