The opposite is true, really. You see tons of (big) SUVs which you did not see as much, say, 10 years ago.
Most SUVs around there aren't based on trucks or minivans.
Over the last decade or so people are increasingly preferring SUVs.
Most of these are soft-roaders, and not trucks or minivans. They aren't very capable off the road. Some of them aren't even 4/AWD, and most are monocoques and not body-on-frames.
