A 20-ft. (6.1 m) ISO container loaded against the drop deck
panel will overload the fifth wheel rating of the M1088 by 4,500
lbs (2041 kg). The ISO should be loaded to the rear of the
M871A3 to prevent stability/loading problems with the M1088.
Failure to heed this warning may result in injury or death to
ope rating personnel.
Refer to the tractor technical manuals that are authorized to tow
the M871A3 Semitrailer for maximum fifth wheel payload, and
required position on sliding fifth wheel notched base, to
preclude possible front axle overload on the tractor.

damage to the equipment.
