Reading through the scheduling of the 4 x 2 and 4 x 4 changeover above, it would seem to me that they concentrated on 4 x 4 CMPs from 1942 on because of the huge quantities of 4x2 Dodge trucks, D15 and D60, that they had available from that point. It would be relatively easy to concentrate production of 4 x 4s as Chev and Ford, and leave Dodge to churn out all the 4 x 2's.

In fact Canadian Dodge production pretty much went the other way, starting with the 4 x 4 D8A, and swapping over to 4 x 2 D15 and D60 types at around the same time the Chev and Ford production changed.
