We have the Lifetime roto cooler. Not too impressed. We were in Moab a couple weeks ago. Temps were 100-102 and the cooler was in the back of my truck the whole time. Because of this we decided to stuff my AO soft cooler inside of it. The fit was perfect and we still had room for 2 days of drinks for 5 people and snacks inside the AO, inside the Lifetime. Each morning we woke up to cold water, but little to no ice. I know it was hot and in direct sun the whole time, but between the two I was surprised with how much water we had and so little ice. The third day we had to drain the cool water and refill with hotel ice machine ice.
