I have driven my truck to the dock in Yokohama Harbor and have gotten aboard the ship. Because I am the designated driver I stay with my truck. That way some one is there to drive on and off the ship. These big cranes hoist your truck aboard the ship. I am assigned aboard the Robin Trent. It is a nice ship and is much to be preferred to life aboard a troopship. On a cargo ship there are no MPs and life is free and easy.
