Custom tractor trailers 1/43 scale

So in late 2023 decided to build some custom tractor trailers for the grandkids and myself.
Since none readily available in 1/43 scale. Lots of HO Scale can be found only but not so much for 1/43. If do find any are scarce and Ebay marked up prices. So got some O scale Metal Tractor trailers and cabs and made some molds and then took the resin bodies and then custom molded a chassis. And presto! they came alive. Took the heavy metal out of trailer frame and replaced with plastic parts. Also took that concept and made some rollbacks. Made 2 rollbacks. I still have the molds so always can make some more.

Here is some build and later pics and also some youtube of them running around.
