The moss covered truck is a 1958 model, probably a Ford F600. This one is either a 1959 or 1960 Ford F850 Super Duty, and also appears neglected. Does anyone know what year it is, 1959 or 1960? Remember, on the 1960 Ford Super Duty retained the same Grille as it is in 1959. All lighter F Series trucks got a new Grille for 1960, except for the Super Duty models.
