The DuraMag® R-Series has all the same features as the S-Series but replaces the swing doors with roll-up/shutter style doors. These are premium, anodized aluminum doors that are customarily seen on high-end fire vehicles. Roll-up doors allow the user to work in a safer position without walking around swing-out doors extended into the street or walkway—no carrying tools out and around swinging doors. Options: Key Fob Locking, Bed Liner
