See a lot of trucks fron the northeast on this site but thought I would start a thread on Macks in St. Louis. When I was a kid it was nothing but fords, macks, internationals and autocars. In the city and a radius up to 18 miles outside of it tri axles can gross 90k and quads can gross up to 112k . Below are some pics. As for tandems you can gross up to 72k.
