Semi pictures for scale
 

Here are some pictures of the semi I used in a pic. It belongs to my son, and has seen better days.

This is an overall side view. I put a Rattler/Stinger/VAMP vehicle in the front since you all know what size that is. And most of the Joe's are 3.75, if that helps. ;)

Here is a closer view. Roy Hornaday Jr.? NAPA racing trucks? Dale Earnhardt association? Cobra is planning something at a NASCAR event!? Noooo! Shocking casualty predictions...

I put the small Cobra jeep on top if that helps for scale.

Another angle, just for fun.

It's a good size truck. Not perfect scale, but close enough for angle shots.

Those are some well maintained vipers.

Almost something you could use as an ARBCO truck.....
