My 2011 came with the 1250# and I didn't think they were to harsh of a ride. Your truck will be of similar weight to my 2011. The 31X10.5R15 tires soften the ride some too if you are running tire pressures to what is on the door sticker. If the tires are class C like my KOs, the door jamb pressure is all you need and is actually a little high. They should be at 33 psi instead of 35 but 35 is easier to read on my tire gauge. The only time I've needed to air them up to 40 psi is when I have a full bed of firewood or 1,350# of retaining wall block in the bed but I am also running 1,750# springs now instead of the OEM 1,250# ones. I've found running 40 psi in an empty truck makes the handling squirrely. 35 psi improved things greatly.
