In the case of your water tank, these are typically sold to ranchers
and farmers. These are some of the most tight fisted buyers in any
industry. Expecting long term durability for something that group
would buy is wishful thinking.

Perhaps this explains why tractors and pickup trucks last only
a couple of years (and purchasing ranchers and farmers have
yet to notice.)
