> All pickups use body-on-frame construction Including the Honda Ridgeline? I thought that was an exception. In any case, you're mostly right, and that design is unlikely to change. Folks who actually use trucks in their work often bolt on various different styles of body: contractor bodies with large storage cabinets on the sides, enclosed van-like boxes, dumping beds, etc. But frames can certainly be made of aluminum. The East company, which makes flat-bed and dumping trailers for semis, makes frames from aluminum. An unloaded, aluminum-framed flat-bed is very noticeable for its pronounced arch. The scratchable surface of the bed will be paint, just as in the steel models.
