My 15 RAM Dually with factory rear air ride with the rear tires at 35psi rode as good or better than a friends 3500 GMC SRW short bed.
Loaded and unloaded the truck rides GREAT!!!
Sounds like you changed your position on the ride quality...
OP,
Depending on your wife's back issue I would seriously consider a Motorhome. If anything you can get up and walk around. We have a Dodge DRW 07 model and that rides terrible and has been retired as a daily driver (because of the ride)to pulls a cattle trailer ever now and then. We even put a Ranch Hand front bumper on it to help with the ride.
