..I guess I don't get it, The SRW truck should ride smoother than the dually, and again, the ride in our 1 ton crew cab, long bed dually is really quite nice and I have tires aired to recommended psi..
on a side note, From what I understand from Engineers in the tire design facet of the tire pressure recommended on the placard, they DON'T recommend one using the 'weight chart" to air tires up on these trucks. They highly recommend using the recommended tire pressure rating that shows on the placard located on drivers side door jamb...The air pressure weight charts are more for much larger trucks and/or trailer tires. My company also manufactures Continental and General Tires and when they collaborate with the auto manufactures, they both agree on a recommended tire pressure ratings...one will back the other as what is stated on the vehicles door jamb for recommended tire psi.
To the OP, what is the recommended tire pressure ratings for your tires? Do you have two placards, (one for loaded, one for unloaded?), or just one placard...have you checked the tires air pressure?
Sounds like you're getting beat to death and that isn't even happening with my 1 ton dually.
