I have driven the central and northern sections with a total length of 52 feet. The section north of Cambria is a challenge but doable with care. The vista points are all on the south bound side and few will accommodate your total length. I would only do this section mid week.
The northern section is more restrictive and the section north of Westport is just not worth the trouble. Go inland at Fort Bragg to Willits. The Oregon coast is no problem. Highway 1 and 101 makes PCH one of the great drives in the country.
