I just sold my 05 Duramax as it had a service body and momma wants a 5er, so I get a new truck and have been doing some research. All the brands will have horror storie. For the most part all mfg have the emissions deal figured out and I consider all equal. The Duramax and PS engine is a better platform than the Cummins since they went to roller lifers in 2019. The Duramax and PS 10 speeds transmissions are VERY similar as this transmission was built as a joint venture between Ford and GM, don't be fooled the the "Allison" branding, it's only "Allison" approved and GM seems to have more issues, mostly valve body related. The new ZF transmission that's coming in the 25 Rams is supposed to be a proven unit that's currently used in many other applications and a major upgrade over the 68rfe. Interior wise, I rank Chevrolet last in comfort as IMO the seats are too hard, even though I love the looks and technology in the truck, the seats just aren't comfortable to me, Ram would be 2nd and Ford leads the way for me. Ride quality, the GM will be the most car like with independent front suspension with Ram and Ford being 2 and 2A. All trucks are capable of pulling anything you want. For me the Ford is the best all around option, but I think most of it is personal preference. Go drive all 3 and pick your favorite flavor.
