A Dominican Republic Dodge M37 light truck up-armoured and armed with a 40 mm Bofors L60 cannon. It was built as a single prototype/proof of concept in 1981 by a naval arsenal called the Naval Arms Department under the leadership of Captain Juan Santiago Díaz Ximenez. (1)

​

The concept for the original vehicle was for a very cheap and light armed vehicle that could be used on rough roads, including in the jungle or smaller urban areas if needed, in a counter-insurgency role. It would have been a faster vehicle than the AMX-13's or M41 Walker Bulldogs then in use and a second concept vehicle using a different hull armour design that was somewhat reminiscent of a BTR-60 was also built as a competitor but was less successful than Juan's vehicle during trials. 

​

Both the Dodge and the other vehicle was not adopted because the Dominican Republic later purchased 8 LAV-150's from the United States instead of using a domestically made vehicle, but the concept stuck around until eventually a domestic APC, rather than a mobile gun system like the above, was adopted in the form of the RM-79 later in 1981.
