|GMC 5500 Series flatbed truck|
The green with orange paint scheme, and its overall condition, make this flatbed truck a "rat rod" candidate. This is a GMC 5500 Series V-Six, possibly from 1968.
This 3d relaxed view stereogram provides a good view of the overall paint scheme.
Regular readers will note that this flatbed is at the same locale as where the Chevy Bel Air and Chevy II were located. Note the use of "were". Both of those beauties have been moved, to who knows where. The photos here capture them for posterity until they can be located again.
Update: the truck has been moved to the other side of the lot.
