besides the water will be splashing around to keep it moving.
I would use 5 gallon buckets and brutes for the water at least.. The rock you can wrap in wet newspaper for the duration of the trip and put them in the empty stock tank.... Get home and fill the stock tank with the water from the truck and some of ur fresh water... get to ideal temp... Dump the livestock (after acclimation) into the stock tank and then.... take ur time (over the next few days) and do the display setup correctly and not rushed. Too many mistakes can happen along the way... let alone if your rushing.
