Southern Oregon Coast recommendation

[DoddsCP]

I am looking for recommendations for a full amenities (50 amp, water, sewer) RV camp along the southern Oregon coast. I would like to to stay sometime this summer, but not the 4th of July week, for about 1 week. Also what route do you recommend I take from Sacramento, CA? From the map it I see 3 choices but I am concerned on which route is better with a 38' 5th wheel.


1st route: Hwy 299 from I-5 at Redding, CA to Hwy 101 north of Eureka, CA?
2nd route: Hwy 199 from I-5 at Grants Pass, OR to Hwy 101 at Crescent City, CA?
3rd route: Hwy 126 from I-5 at Eugene, OR to Hwy 101 in Florence, OR?
