I have a 2007 Duramax LMM all stock and tow a 331MKS. I get approx. 12 US mpg cruising at about 60 to 65 and avoid hard acceleration and take it reasonably easy on the hills. I did hear all the fuss about terrible fuel mileage and think it was all blown out of proportion I have not really regretted buying it. I think it's nice to have the new style body but not the expense of having to buy the urea that is needed for the newer Diesels. Just my opinion
