Handling a long move


Sometime in the next 6 months I will be moving and am trying to plan moving my tank. Fortunately I don't have too much live stock, 2 false percs, a yellow clown goby, shrimp, snails, crabs, sand sifting cucumber, and a handful of small corals. I also have about 60 pounds of LR and 60 pounds of sand in a 3 inch DSB.
Plan A is to break everything down into 5 gallon buckets, load it in the car, drive 8 hours and then set the tank back up. This seems like the simplest solution to me, will this work? If so should I get new sand or can I reuse my old sand? If the purpose of a DSB is to trap and bury the bad stuff, seems like stirring it up and then reusing it could release a lot of undesirable stuff into the water.
Plan B is to set up a 10 gallon nano in the new location and move the live stock first, then move the tank and LR and re-cycle the tank. If I do this I still have the same question about do I get new sand or can I use my old sand.
Do either of these plans seem better than the other? Any other suggested moving methods? Is 8 hours a risky enough move that it would be better to sell my livestock and start over?
