My Snap-on truck is a 1989 award for sales. It is all metal and heavy as hell.
The wheels are huge sockets, the axles are extensions, the drive shaft is an extension and universal joint. The bumpers are wrenches and the headlights are small sockets.
It opens up and contains 4 chrome glasses that say "1989 RA Contest Award" and have a picture of the snap on truck and "Snap-on Brimin' Proud".
I've seen 1 or 2 others for sale, Kijiji and ebay I think.
