You could also use Atheran's bobtails (the old ford C cabs with a dry box all on the same chassis with no trailer) For 28'ers, I go with A-LINE, www.ppw-aline.com, because I like there's the best. Promotex has 27'ers but I don't like them because they have rounded off cornres and are not 28 scale feet long. A-LINE has some trailers that come with decals and also sells decals for the trailers also like SAIA Motor Freight, Yellow Frieght, ROADWAY and ROADWAY Express, G.O.D. (Guarenteed Overnite Delivery), and many more available throgh Micro Scale Decals or Walthers. For the 32'ers, the only one's I have seen are Walthers and I am not sure if they make them still. Check out A-LINES products and you might see something else you could use, they have so much great stuff and detail parts for trucks and trailers.
