The production variant was equipped with a longer chassis and extended cab to accommodate the tank crew as passengers and larger rear wheels than the Artillery tractor and Recovery vehicle variants. 20 ton  Pioneer TRCU20  trailer and 30 ton  Pioneer TRMU30/TRCU30  tractor and trailer combinations were delivered, in both cases with  the trailer  fixed to the tractor. Hinged ramps were used to get the tank onto the trailer, which could be pulled on with the tractor unit's winch.
