I whole heartedly believe they cost way too much, that is another factor I want to see with the 2020 GM trucks... I want to see what pricing they are at. Ford and Ram at the moment are completely insane price wise. If GM would raise their pricing from the mid seventies to high seventies for their top of the line trimmed trucks, I really do think GM could cut into the HD truck shares. I suppose "discounts" are always a factor, but I totally agree, a $75,000 truck should not have some of these problems.
Relatively speaking the biggest issue I've had with any of my diesel trucks has been a 2008 Ram that had a turbo/fuel system blow up at 16000 miles and they tried to pin it on me. They ended up fixing it and voiding my warranty. The day i got it back i traded it in for a GMC diesel... and its been 12 years since I last drove a cummins.
