I recently saw a movie about 3 people traveling around the Southwest in a Splittie VW van.  White over orange, smooth top, but with some cabinets inside.  

The Van was in Terrible shape, but looked to be mostly Hollywood  fake rust and dirt, as the van ran great for the man, son, and father  and dog following a set of directions from the deceased Grandfather to take his ashes to various places to sprinkle.

An "Arty" type film, but the VW was constantly pictured and viewed, and always seemed to be in the picture.  Sometimes from inside, sometimes from outside, sometimes in the background.  Great scenery too, often with the van featured.

Title was "Around the Bend", 2004, with Christopher Walken, now out in video stores.
