I spent significant seat time in all 3 domestics this past summer, and the Ram is far and away my favourite. The coil suspenders made it ride like a large crossover, especially as noted over broken pavement or railway crossings. The Fords I found suffer from unsettling axle hop with no load. The GM was better, but not up to the Dodge. I didn't like the Ford's dash on the XTR's I drove, ergonomics just seemed "not right".
As an aside, I saw a 2013 Ram yesterday with the air suspension, and it looks pretty cool in full low. Looked like a 2wd truck by ride height.
