Was not a big fan of the ford with 6.2 my 2012 was a turd for pulling power compared to my 2016 ram with the 6.4 hemi.Both had 3.73 gears.
Those are both good looking trucks. Every person I’ve read/heard say the Ford 6.2L was weak had the 3.73 gears or was expecting it to be at modern diesel performance. The Ram 6.4L is no slouch. I’ve been in a couple, but they were far extremes; a 2018 Ram 2500 (unknown rear axle) and a 2019 Ram 5500 (4.88 rear ratio really does a lot). I figured the 2500 would feel like a rocket ship, compared to my heavy as Hell F-350, but it wasn’t much different (using the butt dyno). My only gripe about the Ram 6.4L is the damned MDS. As of now, Range Technologies dies have a workaround. If they did, I would recommend it.
