What model Dodge Pickup truck is it in Smokey and the Bandit 3?

At the 22.00 minute mark there is are scene were a father and son driving an old chicken truck get chased by KKK followers in a red Dodge Ram in the comedy Smokey and The Bandit 3. I'm wondering what model is that Dodge in this scene? Is it a long or short bed? Is it a D or W 150 or 200 series?|||1981 Power Ram sweptline longbed. 4x4. It would have been a W100 or a W150. It was hard to tell during those years. My guess is a 150 just because they were becoming more popular.
