They weren't there back in January when I had my lunch date with Miranda Lambert at Rockin Rib in Tishomingo but it looked like they were making it a permanent location because the wheels were off and the trailer was up on blocks. They had also erected a sheet metal smokehouse behind the trailer.
You can kind of see the smokehouse in the pic I took below of a grill they have attached to the back of the trailer. I didn't notice it there when I took the picture or I would have gotten a better shot of it.
