I've traveled over 20 hours before with rays and other fish. They'll be fine. Just keep them warm, well aerated and BRING EXTRA WATER !!, you'll need to do a water change halfway to keep the ammonia down. Stop feeding 3-4 days prior to reduce the amount of waste.
Treat the Bio bacteria the same way, keep them warm and aerated.
When you get to the new destination, setup tank and you're done.
Are you running a canister filter or wet/dry ? if you're not running a canister, you may want to get a large one now. It's easier to setup a canister than it is to setup a drilled tank.
Try to find a 75 gallon non drilled tank now, when you get to the new location, set it up on a cinderblock, fill it with water, put all your media in the canister filter and you're set.
Then you can set up your tank the next day, there's nothing worst than driving for 12-13 hours and still have to setup a tank.
