How big is the tank?
I would get a lot of 5 gallon buckets. Try to save at least 50% of the water in the original tank.
Save all of your substrate and anything else that has the good bacteria in it. Make sure that it has a couple inches of water over it to keep it alive (the big Rubbermaid totes for storage work well for this with a lid).
Save your filter media and keep it wet like the substrate. Depending on what kind of filter you have a ziplock bag works well.
If you can get your hands on a battery powered source so you can keep an airstone in the buckets with the fish in it that would be ideal. But since you aren't too far away I don't think it would be a huge deal.
NEVER MOVE YOUR TANK WITH LIQUID OR ROCKS OR ANYTHING IN IT. It could crack or break a seal on the aquarium.
When you refill your aquarium at your new place, don't use an outdoor hose unless you can control the temperature. Try your best to get the water to be the same temp as your fish were just in.
Be sure to acclimate your fish to the new water, too.
