Neil,
I drove one regular for a while but not a timber jinker, mine were refridgerated freight
have never driven a jinker but have ridden in one, we used to have big road trains
over here with five trailers, I cannot find it at the moment,I had a photo of the rig
and it was turned and could run into it's own backside.................
The models are not really from any particular truck but can be painted to be Kenworths or Macks
or Freight Liners, Just kids toys started for the grankids, enede up with to many people wanting them..........
Roy
