Dont worry too much; remember, these things all survive being mailed. The biggest problem Ive had is pollution from dieoff after breakdown and reassembly and temperature swings while moving - should be ok this time of year.
Ive moved several large tanks and inhabitants;
I used coolers, buckets, trashcans, all half filled and not overpopulated.
I would get a power inverter, and extension cords and the power heads but unless you get stuck in traffic you probably wont need it as youll have water flow just from the truck moving (Id only bother with the pumps if the truck broke down or bad traffic). If you do use the pumps make sure they are secure and dont bounce around and do damage.
Make sure the water alk is good to buffer any pH swings that may occur.
Have a good water change ready for when you arrive home and get set up w/parameters as close to the setup your bringing home. and prepare another change for a couple of days later as a lot of stuff (sponges etc) will die and pollute. Also skim heavy and use lots of charcoal.
