Love the forum!  I'm close to purchasing an 19RAM Limited.  I currently have an 17 Laramie loaded but without air suspension.  My impetus for getting out of the 17 is the "floaty" ride.  It is a soft ride to be sure but I'm looking for a more buttoned down ride.  Now I understand a RAM is not a racecar but I would like a tighter ride.  Can anybody comment on the difference between the new model air suspension versus a prior generation without?  Thanks in advance!
