Garbage Truck
This is a nice little model with lots of little detail. It's 8.5 inches long by 2 5/8 high by 2 inches wide.
There are even little steps on the back for the garbage man to stand on.
Pic above: The rear section of the truck raises up. The lever with the handle on that raised section turns a little compactor arm within the raised section.
Pic above shows the cargo section of the truck where the compacted trash (or Zombies) would be carried.
The dumpster detaches and can even open.
Tanker Truck
This sucker is big.
15 inches long, 3 3/4 inches tall, 2.25 inches wide.
The trailer itself is 11 inches long.
The cab has lots of nice detail and can be used without the trailer.
The trailer and cab together may be a little too large for 28mm, but jack-knifed it does a great job blocking an intersection.
Well, there you go folks. Thanks for looking.
