I have a late 70's suburban hasty bake. If I entered a contest I'd probably mod it by sealing the door, putting on lid/hood gaskets, a deep expanded metal basket for long burns--putting the ash pan on the base of the unit. And probably a slider intake vent on the lower side of the door. And have a wider diffuser.They are taking 30 entries. Only hasty bakes cookers are allowed. Mine is slightly modified.
