Grants Pass to Brookings via Redwood Highway ?

Logging trucks use that road, why couldn't RVs? CalTran has a 45' limit on buses/motorhomes from 101 to the Oregon State line. http://www.dot.ca.gov/hq/traffops/trucks/bus-mh/45-bus-restrict.htm 30 foot kingpin to rear axle advisory for tractor/trailers.

Good road, but not a high speed highway. Gets a little tighter at western end.
Shouldn't be a problem for you.

its a great road with a few curves near crescent city. have driven it many times with a 40 footer with toad.

Did that road a couple of Years back in December. It was just fine!

No problem ... enjoy the view

Just went down that hwy sept 8th. Pulled a 28' 5'er with a Ram CC LB. Beautiful drive. Some tighter curves near the Cali border but not anything to create problems. Grab a tank full of fuel in GP as the CA prices are off the charts.
