I've seen previews for it, but I have no desire to watch it. If they were showing you tips and tricks for making BBQ that would be one thing, but these kinds of people are fiercely protective of their methods and recipes. So I'm sure it would just be filled with a bunch of stupid and pointless drama like American Chopper is, it seems to be the norm for TLC shows like this.
While on the subject, you'd be shocked at how many of these people who do BBQ competitions use Kraft sauce as the base of their own BBQ sauce.
