Got another USA tanker in. I have to swap to KDs right away to run with my other equipment. It's great that USA includes all the screws to convert their cars. Remove the trucks. Screw on the adapter/ spacers and add the KDs. They also have metal trucks that are weighed to track nicely pushed or pulled. They have bronze bushings inside that roll decent. Just remove the USA coupler and re-attach.
I can't pass up a good deal on one. I missed some other cars that ended earlier that evening. Someone got a heck of a deal on their auto carriers.
Maybe someday I will paint and decal some for Stauffer Chem. where my Dad worked.
(I like the MTH tank cars overall. I just wish the trucks were metal or heavier.)
