that stretch has not changed. the worse part is from Leggett to the coast.
if you are an experienced 5th wheel driver, you can do it, since logging trucks/semis drive it all the time.
personally, i wouldn't drive it no matter how experienced i was.
that stretch along with the part north of San Francisco and the part from Carmel to San Simeon, are the 3 sections on Highway 1 not advised for big RV rigs.
check and see what the directory says about Highway 20 out of Willits west, as an alternative.
