I have had my 2017 GMC 3500 DRW Diesel Denali for 1 week, and just towed my 5ver for the first time....WOW what a huge difference from my 2008 GMC 2500 Diesel, which was a great truck with no issues. It was like the trailer wasn't even there...we notice how smooth the ride was, and how much less the truck bounced around from the weight of the trailer.
WE won't even mention all the bells & Whistles this truck has that my old one didn't. However, there are a few downers....the 2017 only has a 36 Gal fuel tank, as my 2008 had a 52 Gal tank (I replaced the OEM tank)...this truck is also harder to fit into my garage as my old truck was a short bed, SRW....but I can live with backing in very slowly. Lastly, DRW trucks don't come with internal tire temp/psi sensors.
We hope to have this truck for a very long time!
