An experimental proof-of-concept truck on a 10x10 chassis, the 73-210 was intended to be used as a wheeled crane carrier. It features a heavy base chassis to allow for most truck-portable crane configurations, as well as a spacious fuel tank for prolonged operation away from civilization. The main drawbacks of this prototype include relatively lackluster suspension and engine armoring, which were intended to be improved before the model reached mass production stage.
An improved gearbox variant that offers a full range of gears at the cost of higher fuel consumption.
An alternative engine featuring improved resilience to damage, acceleration, and power output.
A heavily modernized engine variant tuned for better acceleration and durability, as well as increased power at the cost fuel efficiency.
