I thought it was funny how blatantly obvious it is that the tanker was specially rigged to go sideways like that.

The 1st Chevrolet pickup is either a 1955 or 1956 Apache 3100 or 3600. The 1992-96 Ford pickup is an F-150 with a short wheelbase, not a Bronco. The car is a Ford Fairmont. The second Chevy Truck is a 1973-88 medium-duty C-Series. The gasoline tanker is being towed by an International 9670. The Mayor's car is a Cadillac, and the Spider farm owner's pickup is a 1948-54 Chevrolet 3100-3800, not a Ford.

Some better images of vehicles already listed as well as some new ones. I assume that the images currently up are just from the trailer?

These are all either featured vehicles or background ones known to belong to a character but never seen being driven (like the mayor's car for instance).
