Just keep it in SW...Lots of people have rock shipped, and it makes it ok
Maybe use a heater and a powerhead....you can but an inverter so you can plug them in in your car cigarette lighter....or hook one up to a battery
Thats what I would do...a bin or a few bins for the rock and water...a heater and powerhead and you shouldn't have any die off!!
When are you moving?? Good luck!!
