A truck can be converted into a sport-utility vehicle, but the truck cannot be removed  

With the probable exception of Jeep's unibody-construction Grand Cherokee

it is the general rule for the majority of SUVs on the road

The truck ancestry manifests itself in most of these cars as imperfections in ride,

However, that is evolving. For instance, the new Toyota 4Runner and the similarly sized Toyota

Tacoma trucks only have the same fundamental mechanical layout.
