The set of Hell Hazers II: The Reckoning may look familiar as the water tower from 2.08 Crossroad Blues and the cabin from 2.16 Roadkill are used. The Deer's Head on the wall has appeared in the boys' motel room in 1.14 Nightmare, John's room in 1.21 Salvation, and Steve Wandell's home in 2.14 Born Under a Bad Sign.
In the faux trailer for Hell Hazers II: The Reckoning, writer Martin Flagg is also credited as the writer of Cornfield Massacre and Monster Truck, which are illustrated with images from Supernatural episodes 1.11 Scarecrow and 1.13 Route 666. There's also a shot of the hook from 1.07 Hook Man, of Claire's desiccated hands from 2.07 The Usual Suspects, Gordon and his bloody knife from 2.03 Bloodlust and the inside of Angela's coffin from 2.04 Children Shouldn't Play with Dead Things.
