Talk:Slamvan

Is this the actual truck the slamvan is based on?
Does anyone know if there are other custom GMC trucks like this one (scroll to the bottom of the page for pictures)? Because other ones I've seen on the net like or this one lack the side mirrors that are upside downish and the added bulk that makes the windows so small like the Slamvan in GTASA has. I just wanted to know if that truck is is one of a kind, making it the actual custom GMC the Slamvan was based on.
