they only fall under the definition of "truck" if they are designed as used to haul cargo.
And obviously pick-up trucks haul cargo. Please note ARS 28-5432.B, "This article does not apply to:
1. A vehicle commonly referred to as a station wagon or to a vehicle commonly known as and referred to by the manufacturer's rating as a three-quarter ton or less pickup truck or three-quarter ton or less van..." Note that there is no mention of motorhomes or any exception listed for noncommercial pick-up trucks over 3/4 ton. See, as I keep saying, the State of Arizona SPECIFICALLY lists those vehicles that are exempt. However, some here (I won't use any names) want to believe that only some units are shown as "exempt" but others that fit all other requirements are "exempt" because they believe so. As I said before, Arizona has not been silent on "exempt" vehicles and as a result, their exempt list is all inclusive.
