Man the new Sierra must ride nice, but the journalists still say the rams is the class standard in ride quality. We test drove a 22 ram ltd with air springs, it's a smooth rider. However, I didnt believe it rode better than my 20 nav, which doesn't ride better than the 22 nav. From my experience, atleast before the new ones, the gm pickups ride nice until you hit road imperfections, then the ride quickly deteriorates. I also haven't driven a gm suv with both magnet ride and air springs. every denali we drove had just magnet ride, and as such was just as firm as an expy with base springs, just slightly better riding. Same way our nav in sport mode rides. My dads escalade is just the air springs and from what I remember, it's somewhat lumpy at low speeds but cruises the highway better than anything I've been in so far. I can do a more thorough comparo by the end of the next wk.
