Dodge truck beds from the same generation group can potentially be interchangeable. The truck beds from the 2nd generation of trucks (1994-2001) have the same size and can be interchanged as long as the wheelbase is the same between the two truck models.  Likewise, truck beds from the 3rd generation (2002-2008) pickups are convertible as long as both have the same cab configuration and bed length.  Overall, when looking to interchange Dodge truck beds, it's essential to verify that the dimensions match up with your specific truck.
