re: Why do so many people refer to SUVs as "trucks?"

Some time back, cars went to the unibody design, and trucks still had/have body on frame construction. early SUVs were adaptation of trucks, using the truck frame and adding a rear cabin instead of a truck bed, so we called them trucks too. or, when the first SUVs (vans) became popular for the hippies, we called them trucks, and the grateful dead sang "truckin." and sweet jane was living on reds and vitamin C and cocaine.
