I know what you'll all going through but here's another suggestion. Don't wash any bedding and if you are going to keep them in a carrier, get a big enough one to put a small litter pan inside. You can use a rabbit water bottle for their water. We are also preparing for a huge move (we moved from the eastcoast to the westcoast 4 years ago and are getting ready to go from the westcoast to the eastcoast). Besides my cats, I'm moving with 5 big dogs. Most of my cats will be with my best friends back on the eastcoast until I get there but a few will be moving with us. For those cats, we are setting up 2 cages in the Ryder truck (Ryder is the only one that has trucks where you can go from the driving area to the back of the truck without getting out of the truck. We did that during the last move.) with 2 dogs in their kennels. The other dogs will be with me in my SUV and hubby's SUV will be hitched to the Ryder truck. When we did the first move, we didn't have 2 SUVs and I did all the driving. We also didn't have 5 dogs at the time. With plenty of planning we did a great job. I'm sure we'll be fine the time around. Cats stay in one room and dogs in the other until the truck is loaded, then they get loaded. During the sleeping hours, husband sleeps in the truck with the cats and dogs and I sleep in the hotel (very bad back and I'm real cranky when I'm in pain) with the other dogs. We will have walkie talkies so we can keep in communication. I feel like I've become an expert at moving but I wouldn't have it any other way. Sorry this was so long.
