Have owned a new 2017 Express 1500 quadcab from new, and replaced witha used (11K mi) 2016 Laramie with nearly all options inc air suspension, which did NOT impress me with ride quality. I now own a 2021 BigHorn quad in Flame Red.all have been Hemis, and all 3 have been great and reliable, and amazing build quality and paint finish. Just not happy with the AC on my 21, the others were far better!
