Add 16 oz of liquid to drip tray and preheat Kenyon Grill to high.
Divide the meat into 6 equal portions. Gently form each portion into a 3/4-inch-thick burger. With your thumb, make a 1/4-inch-deep indentation in the center of each as this prevents the burgers from getting rounded tops during grilling. Season both sides of each burger with salt and pepper.
Place the patties on the grill; cover and cook to desired doneness, 2 to 4 minutes per side for medium-rare.
Toast buns on the open side for about a minute.
To assemble the burgers, spread BBQ sauce on the bottom bun, sprinkle on the lettuce and diced onion, place your burger on and top with the pickles and potato chips.
