You won't have any regrets if you get a one ton in Ford, Chevy or Dodge. With these trucks you won't be payload limited ever and you will probably never have a payload/ trailering limit! If money isn't an issue why would you limit your future possibilities. I bought a new Dodge 2500 in 2015 and I'm scratching my head, why didn't I get a one ton!! Fully loaded with my Hawk I'm over GVWR. I just had 2500 on my brain, should have looked at all the parameters more closely. Having said that my truck feels fine with the factory suspension and has an incredible zoom factor with the Cummins diesel.
One example of looking closely at the spec's, I have the MegaCab, it erases close to 300-400 lbs from you payload, however I really like the 4x5' platform in the back.
When I bought my 2500 you could get a LIFETIME bumper to bumper warranty for $3000.00 in the gas models. I got a diesel and that warranty policy didn't apply.
Lots to think about, just don't build in limitations from the get-go, if you don't have to!
