Once upon a time these trucks were top of the line. Now they just sit along the side of the road in a rundown, industrial part of town. The Mack RD looks alright from the curbside but is probably hiding some sort of larger problem.
The R-Model down the street is in a similar spot, quietly rusting away.
My part of the world seems to have plenty of old Macks to spare, most are white and spent the past days in the waste business. Check below for more old Bulldog action.
