I wish it was closer craigslist finds

A lot of times those are old city or county work trucks with the long beds
I think most of them longbed steps of all varieties found their way to the commercial part of the market. Utility compnees, railroads, destruction, etc. Old acquaintance had a Ferd 4x4 crew early 70s vintage, refugee from SoCal Gas. Got it real cheap at their company auction. Very unique, but just as unappealing to look at.
