15+ years ago I needed to move from NJ to FL. The Penske truck was $2750 one way NJ -> FL or $250 FL -> NJ and came with unlimited miles. You can see where this is going.
I rented FL to NJ and did the drive up and down the east coast 4x. The total cost of the move was around $1100 after gas, tolls, and the one way ticket on AirTran. I did it in eight days, including packing the truck and unloading it! What a pain. In retrospect it was probably cheaper to just buy new stuff and just drive my car down.
A harbinger of things to come for NJ? Maybe. It's still there. CA will always be desirable due to its climate and terrain. Lots of international money flows into CA real estate as well.
