There was this guy on the forum a while back that moved from PA to Oregon I believe, and he did it. I know it has been done before, and can be done. Somebody else on here can probably give you better details, but my general understanding is that you put the fish in some large containers (rubbermaid), put an airstone in there, when you stop, do a water change, and if possible hook a filter up for the night. There are also ways to sedate fish, like they do when they ship them, and i believe the right amount of something called clove oil will do that (but i'd do some serious research before trying it). Also, make sure you keep a bacteria colony alive and well from your tank so that you don't have to cycle your tank again in your new home.
