Hwy 395 Hwy 120 and 6.... are they good for a 42' 5th wheel

I've done 120 from 6 and back on a bicycle and it is a real workout but your rig doesn't tire like a cyclist. To bad you can't stop at Adobe Valley and check out the wild horses. The part of 395 through Walker Canyon is a little slow and you will probably have to pull over for the speed demons. Spooner is two lanes from the north side to the bottom on the south side. The Mono Lake Visitors Center is worth a stop.
