Default Chest freezer as water storage tank?

I'm wondering if anyone knows what the R-value is on a chest freezer, and if anyone's ever thought of using one as a hot water storage tank for a solar heating system?

It seems to me that those old gigantic freezers would serve a new purpose as a hot water storage tank for a solar water heating system. but would they be strong enough to retain that much liquid without reinforcement? Or what about half-burying it in the ground to add some strength/insulation? thoughts?
