Wes, I found this listing in my guide...I think the only difference is the upper deck on the trailer being black instead of red, maybe it was a later issue, as I've noticed the Kenworth car carrier listed below it notes black upper deck.



...

Thanks, I have no way of knowing what cars were issued with it. I know I kept some '80s vintage models on it in display, but I had to move some stuff around and pulled these down, which made an opportunity for some pics. Now where to put the pics in the database...?

You could just separate them by their series, that seems to be pretty much how the guide is.
early 100 series were the Rail Route from the 60's
200 series, the 3 inch models
300 series the two packs, though some of the older ones also included small semi trucks
600 series the 1/87 scale semi trucks
800 series, Airplanes
1000 series 1/60 Deluxe Collection
2400 series legends approx 1/32 cars
2500 series grand sport, approx 1/38 sport cars
2600 series Hot rods ?
2700 series dragsters ?
3000 series cars and trucks in larger scale (like your tractor trailer)
There are a number of other series, including 1/24th, and 1/18th models.
