The Medium Tactical Vehicle Replacement (MTVR) is a series of vehicles, based on a common chassis vary by payload and mission requirements. The MTVR is a purpose-designed military vehicle, although a small number of vehicles have been sold commercially for specialized operations such as wildfire fighting.

There were originally four MTVR variants, this increasing to seven, and then nine variants (plus a sub-variant) as deliveries and development continued. A dedicated trailer and prototype/developmental MTVRs have also been produced.

The first MTVRs were delivered in late 1999. The MTVR is the U.S. Marines’ equivalent of the U.S. Army’s Family of Medium Tactical Vehicles (FMTV). The Marines do not use the FMTV; the Army does not use the MTVR. The MTVR was designed and is manufactured by Oshkosh Defense. (From Wikipedia)

This truck is one of two prototypes that were originally developed.
