Bulkhead door was NEVER shut,and during the heat of summer i;d often deliver my neighborhoods in the afternoon and evenings with both the bulkhead and back door open to create a breeze.
there was NO power steering,no automatics and the steps and rear bumper were very high off the ground.this was light years before 'Three Points of Contact" and i'd come out of the truck seeing how far i could shoot myself out when making a stop( my feet and knees are paying the price for this now)
Supervisors and loss Prevention were also much worse about following drivers on area.
