I doubt there is any agreement on what defines an SUV. GM still makes truck framed SUV (Tahoe, Blazer, Suburban) and they have their niche. I think many that had one (including me) got away from them because of their lumbering ride, poor fuel mileage and high step in....all traits we over look if we wanted to tow something with those SUVs. The majority of the SUV buyers doesn't want that. They want a smooth ride with descent fuel economy they can haul the family around in. I don't believe marketing is responsible for the decline of the full-framed SUV, it's consumer demand. Personally, I'd rather have a truck bed than the 3rd row of seating when it comes to a TV.
Huntindog, yes VW, Volvo, BMW, Porche, Buick and Subaru make station wagons thought I use that term loosely.
