Ice Cream!!! Stuff the ice cream. Engels were made by men who drink beer, cold beer, and wanted nothing more than to keep their neck oil cold on a hot day out in the bush. And the meat frozen too for the bbq's. Those two go hand in hand. literally. One to hold the beer and the other to hold the tongs to cook your beloved and then to eat it...
My vote is for Engel just because they have proven themselves worthy for reliability. I want to sell my 32L and buy a bigger one. Now I gotta justify something else to the boss
