does any body know????

Dan, good question - I`ve often wondered why they were called semi`s. The explanations given sound quite reasonable.
Over here in the UK they are simply known as Artics (Articulated tractor unit)

"The cargo trailer cannot move by itself because it only has wheels at the rear end, hence the name semi-trailer: it only carries half its own weight."

See pages 4 & 11 of the Hobby Heaven catalog for some currently available truck kits: http://www.modelcarkits.com/hhcatalog48.pdf

Hi, I`ve just realized that the info I gave about eBay may not be correct (depending where you live), mine is eBay UK - yours may be different.

Hi Snow -Man, There are lots of model Semi trucks on the market. Italeri and Revell do loads of 1:24 scale and eBay have about 3 pages of them (Toys & Games > Model Kits > Trucks).
You don`t show where you are located but there are both European and US models to choose from.

at my LHS they have a lot of semis, but i never really looked that hard at the boxes, but from what i can remember (how the box looks) maybe revell (i saw a peterbuilt model the other day...)....im not that sure.... they also looks kinda older... sry, if this doesnt help much..
