vertical water tank

[fallingwaters]

I need one for the back of the truck---behind the driver's seat on the flatbed seems a good placement from here. I'm looking at the corner vertical ones, they fill from the top and dispense from the bottom, and i can take the truck into town to fill, not the entire rig.

Any brands you like or dislike?

ps--I've read the valves are lousy, and will replace them asap with brass ones.
