Ok, I forget maybe some are set up softer than others, my truck is a SWB ( like 137") with a GVW of about 32K . it was set up bare rails as a Road tractor and it is STIFF as in I pulled the motor and trans ( BB gas) and set them along with 4 tires and the radiator on the back and got ZERO sag.. I mean still right at the top... I KNOW I am going to have to soften mine a bit
