This could result in damage to equipment and injury or death to personnel. • M1113 and M1114 vehicles are not authorized to tow M1101 or M1102 trailers unless they have been retrofitted with MWO 9-2320-280-20-6; Airlift Bumper Reinforcement. Towing these trailers without the airlift bumper reinforcement MWO applied could result in damage to equipment or injury or death to personnel.
