1-16. EXPANSIBLE VAN TRUCK WO/W:
M820, M820A1, AND M820A2
a. Differences.
The M820 expansible van truck has windows, heating and air-
conditioning systems, and uses outside electric power. The M820A1 expansible van truck
does not have windows, nor air-conditioning system; but does have a heating system. The
M820A2 expansible van truck has windows, hydraulic liftgate, heating, and air-
conditioning system.
b. Purpose of the vehicles.
The M820 and M820A2 expansible vans transport
electronic base stations into the field. The M820A1 expansible van can be used for the
same operation. In the traveling position, van truck bodies are 17 feet long by 8 feet wide
(5.2 meters long by 2.4 meters wide). When in the field, van sides are expanded to give a
width of nearly 14 feet (4.3 meters). They may serve as communication stations or
electronic repair stations. The vans are designed to carry up to 5,000 pounds (2,270 kilo-
grams) of equipment into the field. The M820A2 expansible van is equipped with a
hydraulic liftgate, which makes it the preferred vehicle to use when heavy, delicate
electronic equipment has to be moved in or out of van.
c. Performance.
All three expansible vans have a minimum turning radius of 47 feet,
4 inches (14.54 meters, 102 centimeters).
