Kinda scratching my head on this one bevaothe spare tire side mount was first offered in 53, but the illustrations only show 54-55?
Notice that the date on that drawing that Dan posted is mid-year 53 (meaning 54 Model Year), as is everything else in the FAM. The side mount spare bracket may have been offered in 53 but would have been slightly different to account for the sloped top bedside.
Other than that side mount, the FAM doesn't have anything on the bed, as well as some of the accessories you mentioned. There is an accessory catalog floating around somewhere (one of the old guard stovebolters has posted pics from it) which might show some of the accessories. Not published to buy though.
