This set of HO Scale Super B flatbeds is typical of the type seen in the industry, with the lead trailer at 28' 6", and the rear trailer at 32', with a 102" width. The beds are recessed, to allow the builder to add thin wood for decking, which is not included of course. The file has passed all the normal software checks, but should there be a problem, feel free to contact me via the designer link, or directly via email to modelmechanic@gmail.com.
