Denali Detuned
I found the answer.
Yes the payload is lower because the standardly equiped Denali is a bit heavier.
The 5th wheel capacity is 1,100lbs less because all the Denali's have been manufactured to meet California emission standards----ie, detuned; by how much I haven't found out yet, but it must be substantial.
