In the USMC circa 1992, we never had CTIS on anything except the Hummers.
CUCV was basically a civilian vehicle built to a military spec for ADMIN and BASIC transportation uses. It was never intended for a combat role. It was more of a cost saving venture than anything else. IRC, a CUCV was about 1/3 the cost of a Hummer. These CUCV would be square body chevy pickups and blazers from 1983-1987. There was a VERY limited number of "CUCV II" built on the GM400 platform but I never saw one in the USMC. Possible that the CUCVII's had a CTIS but I dont know.
The Main purpose of the CTIS in the military was to air down/up tires as needed for traction and environmental issues. The USMC implemented this on new hummers put into service around 1992(???) If your tire was shot it was not going to get aired up again by the CTIS. That was why we had run flat tires/rims. The run flat rim was an important part of the CTIS system. CTIS could be used to keep tires at a constant and help with slow leaks. Our bigger trucks, 2.5 and 5 ton, had on board air systems designed for external air use such as brakes, tools and inflation.
