Mine is a cheap Coleman water cooler that will provide ice cold drinking water throughout the day. It fits between my dash and side mirror in the driver side. I use it for a beverage cooler when the weather cools down and I’m not sipping on water all day. There’s no reason to waste money on Yetis, Rtic, etc. Those are expensive overkill that really only benefits deep sea fishermen or other people that must have ice for days but won’t have access to it otherwise.
