I guess MTH has made a licensing arrangement with American Heritage. Not a bad move, although it does little for me" I've got several of all of them but the newer SUVs, which are far too new for my layout. The DIVCO trucks are by far the most interesting. I have three, one converted to 'Streets. They are rather difficult to take apart: the interior holds the six doors in so when you take it out they tend to fall out and are hard to get back in.
Anyway, I would like a big flatcar with a load of three Divco trucks - that would be neat. Maybe MTH will offer that.
