Most black hwys in NV are good. We did 447 a few years ago in a class B MH. Highway is nrrow in places. Below is my day log info.
Day 1 - Thursday, September 1, 2011 On The Road
Out of Fallon at 9:10 AM PDT heading West to Fernley then North on 447. Quite a bit of traffic on 447 due to Burning Man at Blackrock Desert, Once we got past Gerlach heading to Cedarville a lot less traffic. 447 is a shorter route, but you can’t make as good of time on it. 190 to Cedarville, four hours. Had lunch at Country Hearth Café/Bakery. We Stopped 14 miles S of Lakeview at Goose Lake OR SP site # 13 w/20 amp electric & water $20.00. This is a nice park, sites do not have lake view and showers are not the best.
