📚 Vehicle History

Dodge Truck Legacy:

Dodge has a long history of producing robust and capable trucks, dating back to the 1930s. The Ram nameplate was introduced in 1981.

Second Gen Ram Launch:

The second generation Ram (DN platform) debuted for the 1994 model year, significantly redesigning the truck with a more aerodynamic and distinctive cab design. The Heavy Duty (3500) models were introduced on this platform.

Second Gen Ram Updates 06-07:

The 2006-2007 models represent later iterations of the second generation, featuring updated engines (introduction of the 5.7L HEMI) and refinements. The 5.9L Cummins was still a dominant diesel option, with a high-output version available.

Manufacturing Location:

Saltillo, Mexico; Warren, Michigan, USA (production locations varied for the Ram series)
