I live outside tracy, great info here, that being said I have made the trip you describe both pulling my 25 fifth wheel and my
Casita. As long as you avoid the weekend in the Bay Area you would be good.
I have done 92 with no problems..
Going home up I5 is easy. The trip through Sacramento is easy, as there aren't many lane changes..just avoid commute time.
One of m favorite places to stay is San Mateo Memorial Park, but they don't allow dogs. It is a bit south of half moon bay. And not right on the water, but the little town of Pescadero is neat! Archangelos bakery makes the most awesome artichoke sour dough bread..that, some cheese and some wine makes an awesome meal.. plus you are probably less than ten miles from the ocean in the redwoods.
