U.S. Highway 17 Coastal Hwy from Savannah GA thru S Carolina

It should be no problem at all for you. I took it going south several weeks ago with a 32' class C, and I don't recall any real difficulties or hardships.

The road is much less curvy and far more inland than CA route 1. You don't have ocean views, and indeed are generally a few miles or so from the shore. It's generally scenic-ish, but not spectacular in the way that much of CA 1 is.
