Jane,
Very easy to explain in 2 ways:
1. 4 tires with 65-80 PSI will not flex nearly as much or easily as 2 tires with the same PSI on road imperfections and transfer the higher degree of jolting to the truck vehicle's stiffer springs and shocks which do dampen some of it but far from a lot or most. If the springs and shocks were really efficient, you'd not feel hardly any bumps or road imperfections when riding as the lesser spring capacity and smaller dia piston shocks of a lighter capacity vehicle would absorb so much more of the axle/tires transferred quick motion. IE, nice Cadillac type ride! A far more jolting is felt when the vehicle is unloaded than when it's loaded heavy. Simple physics! Rear axle capacity itself can be the same but the suspension required to carry the higher weight is very different. Just in a nutshell!
2. Go test ride each for 20+ miles, a 3500HD SRW and a 3500HD DRW truck empty having max inflation in all rear tires as you'd have hauling heavy and test ride on the same bumpy roads at the same speed and let your body, behind, and mind explain to you the difference.
Regardless of what BS you hear or read, a vehicle sprung for 13,000+ rear capacity having 4 rear tires on the will not ride the same empty as a same type model/brand sprung for a max of 10,000 rear capacity having only 2 rea tires. Why do you think they even put 2 more wheels on a truck as they are not for decoration!
You will not be deflating (like so many claim you can do) all your tires every time you stop for the day or a couple days at a CG for driving your truck around empty and then the next morning re-inflating them again. If so, you'd see so many DRW truck owners inflating their tires in CG's everyday and it just doesn't happen and never has in our 52 years of RV'ing. It's even a pain and takes time (even more with duallies) to do it when you go RV'ing for a weekend or so and then want to drive the truck empty during the week etc. Talk is cheap but seeing it not being done speaks for itself! Observe for yourself!
Also to add, you'll have 6 new tires to buy rather than 4, or 50% more cost each time but having 4 tires on the rear can be of a help if one blows out but then the one tire must carry the load of 2 tires and is compromised/ruined real quick. If it's the inside rear tire that blows or goes flat, remember that the outside tire has to come off too! More fun! Having 4 on the back doesn't do anything/or help with a blow out/flat on the front and those are your steering and control tires. I'd much rather a rear tire blow anytime or go flat than a front tire! No dual tires on the front in true production pickups!
More to it than just ride quality but if a DRW truck is actually REQUIRED to haul the load, that's what you need to have. Both SRW and DRW trucks have positives and negatives depending on your needs, wants, desires, and actual uses.
