Went to Johnsonville's website and found this info:
The Big Taste Grill is 20 feet tall, a whopping 65 feet long and 6 feet in diameter. Just to park it you need a space that is 20 feet by 90 feet!
The 6,000 pound lid with an 8-foot handle is opened using a hydraulic system, giving access to 440,000 BTUs, which is needed to grill the 1/2 ton of Johnsonville Brats held in the onboard fridge.
The Big Taste Grill can cook 2,500 brats an hour or 750 bratwurst at a time on its 40 square feet of grilling surface. That's enough to keep a festival satisfied for a while!
The Big Taste Grill sports hot and cold running water, a huge clean-up sink and a frosty cold refrigeration unit.
To give the chefs plenty of room to move about as they grill the flavorful sausage, the grill has a 4 foot aluminum walkway along its border.
