R = Recruit series; original designator for a "Recruit Series" on announcement day, May 25, 1993.

VL = Value Leader; began using this designator for Recruit Series 2-Dr. & Open Top very shortly after announcement day. "VL" was also used in 1994-1996 Model Years to simply designate the "Base Model" 2-Dr. & Open Top.

HM = HUMMER; at one point AMG called all variants of their HMMWV design vehicles, HUMMERs

C = Commercial; sometimes referred to as the "Civilian Version."

F = Fleet/Industrial; sometime referred to as the "Commercial Version."

4 = 4 side doors

2 = 2 side doors

S = Station Wagon; most often simply called the "Wagon." Early Model Years had a rear liftgate and a tailgate. Later Model Years had two rear Vertical Doors, sometimes referred to as "Barn" or "Swing-out" doors.

SB = Slant-Back; 4 (side) doors plus one rear Slant-Back (hatch) door.

O = Open Top/Body; sometimes referred to as "Soft Top." When an "L" preceded the letters "CO" in the model code, the side doors were termed "Soft" meaning; metal and vinyl construction. When an "M" preceded the letters " CO" in the model code, the side doors were termed "Hard" meaning; all metal frame construction.

X = Enlarged 2-Dr. cab - 6" longer. Sometimes referred to as "Extended Cab."

NOTE: Don't confuse alpha-numerical designators within a "VIN" and AMG's alpha-numerical "model code/UPC" designators. There is not always a direct correlation. There are some States that even consider all H1 models with an "open area" in the rear as "pick-up trucks" and when that area is "enclosed," it becomes a "Wagon." Go Figure!!!
