Moves are no fun.
I've moved my 55g twice. Both were about six hours worth of driving.
What I did is I put the live rock and a little water in a big cooler. The rest of the water went in capped 5g buckets. The fist and inverts (2 clowns for fish) went in a 10 gallon with a heater and powerhead that I plugged into the car. When i got to my destination, I set the 55 up, and got the filter and heater running, useing the old water. I also mixed new water for a water change. Live rock went in as soon as the water got somewhat warm. The fish and inverts waited till morning to go in, after a water change.
It worked really well, didn't lose anything.
