Is the ice somehow separated from the food - like on a tray or something? Seems like you still would have food ruined by water or am i missing something?
I love the idea of it draining itself. Did you ever try draining it to a bucket or something to be used for bathing? Maybe problematic due to spills?
Short answers: No, yes, and depends on where the bucket is.
Long form: The only thing physically separating the ice is the bag it comes in. Water does trickle down over the food (which is in containers or wrappers), but it never gets deep enough to swamp the food and seep into the containers. (You know how no matter how many Ziplocks you use, water still gets in? That hasn't happened with this method.)
According to most conventional ice chest wisdom, this is not the most efficient way to use ice. They say it should be emptied into the chest to fill in all the little spaces for the most effective cooling. Placing ice under as well as on top of the food is also recommended.* Most often, draining the cold water is discouraged. HOWEVER, in practice, whatever efficiency I've lost is more than made up for by the convenience! I just don't like having to dig through ice to get to something, then make a "hole" to put it back. Lifting the bag and grabbing what I need is so much easier!
*If you're heading out from a S&B base, you can freeze some stuff to put on the bottom and plan to eat it two or three days later.
Yes, we have put a small bucket under the van below the drain hose when parked where a puddle might be a problem. Even on pretty hot days, it hasn't amounted to much, but it could certainly be saved for reuse. I do pull the rear window thermal curtains, and sometimes put a pillow on top of the cooler to keep direct sun off.
It has been a few years since we've spent much time far from a source of ice. We do need a bag every two days during hot weather to keep our most perishable items good and cold. When we spent weeks away from ice in days past, we relied on shelf stable items.
