This is a Tandem axle version of a Fuel Lube truck body. This one offers an open back, and I offer a companion detail set to go with it if preferred. I designed it this way so the buyer can choose to detail it himself as he sees fit. It can also be displayed with the door open or closed. It is NOT necessary to order the detail set however, but an option! This set has passed the normal software checks, but should there be an issue, contact me via the designer link or directly to steve Nasburg at firstname.lastname@example.org Be sure and follow me as a designer to get the latest updates and easy access to my store.
