I would agree that the show is not terribly well executed. I found the BBQ Paradise episode to be more informative. As I understand it, the cooking methods at Kreuz and Smitty's are far more different than just the locations.
I did enjoy the exchange with Smitty's grandson (Pit man at Smitty's) about the sausage recipe.
Host: So do you follow a secret recipe for you sausage
Pitman: Yeah, we've got one, it's usually about 85% beef and the rest pork. Although it varies and even some days it is all beef.
Host: Why don't you always have the pork
Pitman: Cause some days I don't feel like cutting pork
