Hmm.
Seems like all livestock is small.
I would get a bunch of 1 gallon wide mouth containers, a 5 gallon sealable bucket, and a couple of large cheap styrofoam coolers.
Put all the corals and fish in the 1 gal containers, and put those in the coolers.
Put a few inches of water in the bottom of cooler, and a temp sensor.
That should be manageable for hotels, trailers, moving, and so on.
Buy several hot packs or ice, to adjust temp as needed.
Then:
Map out some fish stores in cities on the way. Buy some salt water and store in a bucket.
Try to do 50% water changes twice per day.
When you get there, you can still keep livestock in containers as long as you do water changes.
The fluctuations in temp and so on will be hard on things, but not as bad as ammonia buildup.
As long as car and hotel are in the 75-80 range, probably fine.
