Engel 35-Quart Ice Box
Coolest Points: It’s rotomolded and packed with two inches of polyurethane insulation. After 26 hours, the temp inside was still 39 degrees, easily the coldest reading. The big drain plug works well because of the cooler’s slope. Circular rubber “feet” under each corner kept the cooler from sliding around the truck.
Lukewarm: The drawbacks of insulation are weight (the cooler weighs 22 pounds when empty) and the loss of interior volume. No sliding in the truck bed and on deck also means no cheating when hefting the cooler around.
Tip: Use the latches — they’ll keep kids from opening the lid for no reason.
