It's that exciting — yet bittersweet — time of year when the NASCAR season comes to a close. The racing's been incredible, the memories unforgettable, and now it all comes down to Phoenix! Three series, four drivers each, and one last shot at glory.

In Trucks, can Corey Heim cap off a historic season of domination, or will underdogs Ankrum or Honeycutt pull off a championship upset?

Plus, an exclusive interview with Xfinity Champ 4 driver Carson Kvapil, the Paint Scheme of the Week, and Fast Davey's Bets as we wrap up another thrilling NASCAR season.
