Water tank size & placement

[Ozarker]

Larger amounts of water in a blader like 50,75,100+ gallons should be centered and low in the vehicle. Putting it on one side to counter weight of other loads on the sides will give you an off balanced vehicle as you use the water.

I have about 20 -5 gallon bags for emergencies in the house. Amazon has a large assortment of bladders.

Wow, those bladders are a LOT smaller than I'd have expected for how much water they hold!

The moral of the story is that you might as well have a plastic tank for your expected use (they aren't heavy at all) but you can carry extra in a bladder if necessary.
