In a town where steel mills are prominent, yes.Oil field towns as well.In Cleveland, Ohio, there are a few local companies that had a few o/o's with 10 and 6 wheel flatbeds, and did real well.I was real close to taking my box off and changing it to a flatbed, back in 1990.
Than I was at Ryerson steel one day, picking up flat coils, and sitting in the warm truck, while it was snowing/sleeting/cold/windy outside, and watching flatbedders rolling their tarps in that mess, and thought, "Screw that!!!!"
