The above are NOT Medium Duty Trucks. The Engines/Transmissions may be used across categories but if they are in a light duty truck it is still considered light duty. See Below: Source Wikipedia.
"In the United States, commercial truck classification is determined based on the vehicle's gross vehicle weight rating (GVWR). The classes range from 1–8. Trucks are also classified more broadly by the Department of Transportation's Federal Highway Administration (FHWA), which groups classes 1–3 as light duty, 4–6 as medium duty, and 7–8 as heavy duty. The United States Environmental Protection Agency has a separate system of emissions classifications for trucks"
