GM has not been a serious contender in the medium truck market for some time. Very few of their dealers sold or serviced their medium entries. The heavy truck makers such as International, Pete, Kw and Freightliner have taken most of the market because they have the sales and service support. Someone who is equipped for class 8 trucks has no trouble servicing medium duty trucks. And then there are the imports beside Isuzu like Hino. Furthermore, it has been many years since GM has had an appealing engine offering for medium class trucks. In my opinion, getting out of the medium market is the smartest move I have seen by GM so far.
