Mine Resistant Ambush Protected Vehicle M1224 MaxxPro.

The tall height of the M1224 is one feature that helped it mitigate blasts from mines and buried improvised explosive devices, as the space between the hull and the mine allowed the force to dissipate before striking the vehicle. Two armored windows are present on each side of the passenger compartment, and each of the front doors was also provided with one. The windshields and door mirrors were heated by wires in the glass which were activated by a timed switch. The door mirrors could be adjusted from the inside. The objective gunner protection kit (OGPK) fitted to this vehicle was traversed in azimuth by an electric motor. The fuel tank is located under the step beneath the driver's door, and the mesh screen protected the vehicle's air conditioning condenser. Stowage boxes can be seen in front of and behind the rear wheel. (Picture from MRAP Vehicles Handbook: Tactics, Techniques, and Procedures.)

The vehicle's four 12-volt batteries are housed under the step beneath the right-side door. The stowage box in front of the right rear wheel is home to a 110-volt power inverter, NATO slave start connector, and air hose fitting. A 110-volt AC outlet is housed in the stowage box behind this wheel. (Picture from MRAP Vehicles Handbook: Tactics, Techniques, and Procedures.)

Stowage for water cans was provided on each side of the rear entry ramp, and stepladder loops climb each of the rear corners of the hull. The hydraulically-actuated ramp took a very long 17-19 seconds to lower, which was improved on later Navistar vehicles. (Picture from TM 9-2355-106-10/TO 36A12-1C-2400-1.)

The vehicle frame and powertrain are sketched here. The 530in³ (8.69L) engine had a bore of 4.59" (11.7cm) and a stroke of 5.35" (13.6cm). (Picture from TM 9-2355-106-10/TO 36A12-1C-2400-1.)

Looking forward into the passenger compartment, the offset seating can be seen as well as the stowed gunner's platform. This platform could be raised when needed to allow the gunner to take his position through his roof hatch. (Picture from TM 9-2355-106-10/TO 36A12-1C-2400-1.)

The driver's instrument panel and switches are shown here. 1. Rear crew light switch. 2. Spotlight control toggle. 3. Spotlight switch. 4. Rear door/ramp switch. 5. Rocker switch with four arrows and rocker switch with two arrows [for door mirror adjustment]. 6. HVAC pressure gauge [to measures cabin pressure; normal overpressure is 0.8-2.8 wc (200-700Pa)]. 7. Fuel fired heater timer. 8. Infrared controls. 9. Fuel fired heater switch. 10. Parking brake switch. 11. Trailer air supply switch. 12. Air cleaner gauge. 13. Battery voltage gauge, 24V side only. 14. XFER switch [to put the transfer case into high, neutral, or low ranges]. 15. Front axle switch. 16. EXH brake switch [the exhaust brake is disabled, but its switch remains]. 17. MIR heat switch [to defog windshield and door mirrors]. 18. Main power switch. 19. Ether start button [to inject ether into the engine when trying to start when the temperature is below 32°F (0°C)].

Not labeled are the steering wheel with the cruise control Set/Cruise, Resume/Accel toggle on the right-hand spoke (the Cruise/Throttle on or off switch is on the opposite spoke); and the trailer brake hand control emerging from behind the steering wheel's right spoke. The throttle control and service brake pedals are in their usual location, and the pushbutton transmission selector display is drawn directly to the right of the throttle pedal. On the dash above the throttle pedal is the ignition switch, and the master vehicle light switch is the cluster of buttons above the EXH brake and MIR heat switches. The fire suppression system controls are to the upper right. (Picture from TM 9-2355-106-10/TO 36A12-1C-2400-1.)

Compared to the above vehicles, the applique standoff MEAP kit is obvious on the door and passenger compartment. Note that the door handle now extends below the armor kit since it covers the handle's previous location.

The increased width imposed by the MEAP kit can be seen when looking down the side of the vehicle. The outlet for the cable of the electric recovery winch is in the front bumper, and the spotlight is above the driver in front of the OGPK.

An armored window was placed on each side of the rear ramp, and the bottom step of ramp itself looped over the roof when closed. The black muffler can be seen behind the tow pintle, and the engine exhaust pipe exits to the left under a guard. More details of the MEAP kit and how it is mounted can be seen.
