Best way to move live rock??

[findingnemo1]

Hi everyone.

we are moving on the 24th and i am a little concerned as to how to move the rock to minimize die off.

We have 3.5 hours to drive and are useing a uhaul so am not sure how to do this as that truck is going to be really cold.
The fish and corals are all going in rubbermaids in the van but i have 100+ pounds of rock that i am not going to be able to fit in the van with water.

Suggestions?

Thanks
Lisa
