Personally, I think you're heading in the wrong direction. We left the West Coast (lived in CA, WA & OR) in the 80's and headed to Georgia. Even today, nearly 30 years later, we're so glad we never moved back to the PacNW.
Jobs for myself, DH and our children have been so much easier to find and keep here in the southern states. CG rents are also much lower...
But definitely take the route slow. We typically travel 4-6 hrs to enable us to park and set up before 2pm when the mad rush for spaces from other RV travelers fills up the remaining sites.
