So.... Why not just rent a potable water tank truck? I would think
they must be available. And you can probably get one that holds
more than 1000 gallons too.

The problem with the Hertz water tank trucks is that they only have
2,000 gallons, which (a) requires a class A license, and (b) they say
they would never recommend you drink out of it because they're mostly
used as sprayers at construction sites.
