These trucks Rcsb have come a long way. Now it’s not as nice as a 4 door but it’s close. seats are not bad and there is room behind the seats too. Mine is a 22 xlt 5.0 4x4 Rcsb. 2wd would probably ride a little better but I bet it would be marginal.
My truck rides damn good for a short truck. I spent a couple of weeks dialing in the shocks, but it is good now. I have mine set on the soft side and my suspension is not at slammed as some of these guys. I wanted a little more travel in the rear.
In stock configuration my 23 xl rcsb 5.0 2wd was pretty comfortable, seats are pretty decent with room to spare even with being 6 foot tall. The ride is comfortable enough, a little more springy than a longer wheelbase but definitely not bad
When it comes to ride comfort, it is very subjective. You really need to go drive one on a long enough test drive to determine if you're ok with it. Having test drove a RCSB and a SC 6.5 bed back to back, I can assure you there is a very noticeable difference in ride quality and road noise. I wanted the RC but ended up getting the SC. You really have to drive it yourself to see which you like better.
