I have an 2003 and a 2016 duramax. I’ve been very happy with them. The 2016 average mpg for combined city/highway the last 30k Miles is just over 19mpg. I swore off Super Duty trucks after getting screwed by ford and stranded every time the glow plug controller went out. (It was a known problem they chose not to resolve—I went through 6 before trading the F350 in on the 03 duramax). Always been a fan of the Cummins motors....just not the the package they wrapped them in. I concede the dodge has the nicest ride and interiors/pricepoint. It’s just that reliability comes first. If Toyota sold a 3/4 ton diesel truck, that’s what I’d be driving. I know that’s heresey in many circles, but that’s our experience with Toyota vehicles.
