Saw these at the store today and bought two (mainly for brisket packers that I pull and want to keep hot). They're called Coleman Party Stackers. They're intended for a case of soda/beer cans, but they looked about perfect for whole briskets. Put a 9 lb. bone-in butt in there today--triple wrapped in foil and two kids' beach towels (with a third to take up dead airspace), and it appeared to work out.
