I was going to edit my previous post to add information about the monster sausage vendor, but thought, as far as cooking hardware goes, this thing is surely gluttonous.
Juicy’s has a mobile grill that they drive to special events. It is called the Outlaw Grill. It is quite spectacular. It can cook 1,000 items simultaneously.
If you ever see it at an event, make sure to stop and get a monster sausage.
