While I'm not opposed to adding any new hardware, there are some practical considerations. These trucks were not nearly as mobile cross country as the halftracks, and were not used in direct assaults. They were used to move troops operationally, not tactically. They were used only on improved surfaces (i.e. roads) for the most part, something not modeled in the game (as I've suggested in an earlier post, I'd love to see terrain affects added to GV movement, in which case +1 on adding trucks).
