Had a 2003 Silverado Duramax 6.6l diesel...had been used to plow snow....when it desolved on the road we got talked into a new 2012 Ford F250 gas truck by a slick salesman (..."it'll do all your 2003 diesel would do, and for less money"...). Nothing against the Ford, probably did all it was supposed to do...just not what he said it would do! Drove to Florida one year and got to hate the thought of getting into it, let alone driving it. Couldn't pull our fifth wheel up a hill, shifted every time we went over a painted line and got about 7 mpg (was told it do 11-12 mpg). Before you say I was gullible, trust me I know, paid for it BIG time. After a year bought the truck I should have in the beginning...2014 Silverado Duramax 6.6l diesel....now I'M a happy camper!!
