World’s Largest What?

When we made our motel reservations for the night in this town…we had no idea that this roadside gem was just down the street. Do we lead a charmed life or what?
UPDATE: This is “The World’s Longest Barbecue on Wheels” sitting in front of Big Boy Toys in Magnolia, Arkansas.

I still don’t have any idea what that is????
