Hwy. 20 Willits to Fort Bragg, Ca. ???

You will not have much fun nor will anyone who gets stuck behind you. :E The road is very tight and keeping that much rig in your lane and off of what little bit of shoulder there occasionally is will be a challenge. Please keep in mind that crossing the double yellow at any time is simply NOT an option. I would recommend you find an alternate route but then when you get free advice you pretty much get what you paid for. Good luck.

As always.... Opinions and YMMV.
