I've seen AZ Wingrider's setup and it's pretty good.
I'm from Texas and accustomed to hot weather. I didn't need that much of a container and DIDN'T want a "Big Gulp" hanging on my handlebars. I mounted a bike water bottle cage on a piece of metal and bolted it to the right side passenger peg location.
If you do something like this make sure you get a water bottle, or whatever, with a straw so you don't have to lean your head back to drink.

Lastly, on longer trips, I carry one or two 32oz Nalgene bottles somewhere in a bag.
