At least as recent as the Advance Design years, Cantrell made a special body type that was shown in Chevrolet truck catalogs. They made a very handsome "Custom Station Wagon Body" that could be called a woody Carryall Suburban on a 3600 and a 3800 chassis (125" and 137" wheel bases). The body lengths used on these chasses varied.
Here is a picture of a 1952:
