Dodge Bighorn CN/CNT950

 

Shown above, 1 of 2 prototypes, CNT9500, and the first Bighorn sold to the public.  This truck was used for all literature and is currently being restored by Tony Youngblood. This truck was purchased new by Jim Roop.      

The breakdown of sales figures for the Bighorns are as follows.   

1973

1974   1975

8 Sold in the U.S.

91 Sold in the U.S. 91 Sold in the U.S.

2 Sold in Canada

25 Sold in Canada 43 Sold in Canada
1 Sold In Mexico
   
The grand total being 261 Bighorns produced between late 1972 and May of 1975 when Dodge ceased production of these trucks. Short lived but making these trucks today rare and highly sought after. Based on registry numbers and Bighorns that we still know to exist, there are approximately 105-110 of the 261 left. Several are in the process of being restored, while several others are sitting and rotting into the ground, still intact but too far gone. The price on these trucks continues to rise, especially with the demand and lack of Bighorns on the market.  In the mid-90's my father, Tony Youngblood, wrote an article for Wheels of Times, in which it was only partially published, but gave a breakdown of the Bighorn, from drivetrain and frame assembly to appearance items. The same article was published several years ago by Old Time Trucks in full and was at one point, the article on this page. As the time comes for more information on the Bighorns, it has now been moved to a separate page and another article, One Of A Kind, on the first Bighorn, is in the process of being added as well. This article was published in the very first issue of Shifting Gears and that issue recently sold out.  Please Note: The information on this page is not complete but will hopefully be soon.
