interesting: chevy didn't have fleet trim until 58 and while i've seen quite a few chevy fleet trim trucks they all had steps, none of the gmc fleet trim trucks have steps. they look surprizingly good sans steps
redefines the term 'stepside bed'
not sure what yr this is, it may be a prototype fleet trim
no steps on this 58/59 gmc
also note the kick vent grill delete for the gmc fleet trim package
