Does a 2004 Dodge truck bed interchange on 2006 Dodge?

Yes, a 2004 Dodge truck bed can interchange with a 2006 Dodge truck, as both models belong to the same generation of Dodge pickups (the Dodge Ram). However, it's important to ensure that the bed size and configuration (like short bed vs. long bed) match between the two trucks. Additionally, minor differences in features and mounting points may exist, so some adjustments might be necessary during installation.
