here's a possibility of why they haven't done a diesel fullsize SUV. No SUV has been produced with a diesel because it is known that many people need a diesel for specific reasons and in that case must buy one of the available trucks on the market(Chevy/GM, Ford, Dodge). a lot of people who buy these large diesel trucks also own a second car that is either a. more practical or b. holds more people(burban). If a Suburban was produced with a duramax it would eliminate the idea of some people owning both a diesel truck and a people mover since it is a perfect compromise. In my mind the thought of a duramax suburban is almost to practical/smart and companies like chevy would rather take a shot at customers having to buy a 2500hd and a tahoe instead of just a dmax burban
