Duty cycle. Same thing as medium duty trucks have the same engine in them as a class 3 truck but is detuned to less HP.
Not true. Its actually noise related. A Ford Powertrain engineer answered that question a while back on one of the Ford forums. The engines are identical under and over 10k gvwr, but over 10k they are rated at a lower RPM for noise reasons. Dumb yes but true.
