The MaxxPro Plus model comes with dual rear wheels for increased load carrying capacity, such as an ambulance or EFP protected variant.

The V-hull deflects the blast of a land mine or improvised explosive device (IED) away from the vehicle to protect its occupants.

Because the chassis is mounted outside the armored crew capsule, there are concerns that it will likely be destroyed in the event of an ambush, leaving the soldiers inside stranded.

[7] According to Navistar Defense, the vehicle is designed with operational readiness in mind and uses standardized, easily available parts, to ensure rapid repair and maintenance.

The MaxxPro's high ground clearance provides greater protection from underbody blasts, but also raises its center of gravity, causing rollovers in certain situations.

The ESC combines road factors, vehicle data, and driver intent to automatically correct driving to ensure stability during maneuvers.

Following testing, a first order for 1,200 MRAP Category 1 MaxxPro vehicles was placed by the US Marine Corps Systems Command on 31 May 2007 for delivery by February 2008.

[11] However, as the U.S. Army Research and Development laboratory is overseeing the entire MRAP program, it is unclear which branches of the US Armed Services will be receiving the vehicles, and in what numbers.

[21] The company is also pitching the MaxxPro to replace the M113 in units above brigade level not directly involved in fighting for the same cost saving reasons.

[23] On 4 September 2008 the U.S. Marine Corps awarded Navistar a $752 million contract to develop and produce a lighter, smaller, and more mobile MaxxPro variant that is less prone to the rollover problems that have plagued MRAP vehicles.

On 5 May 2011 Navistar Defense received a $183 million delivery order for 250 International MaxxPro Dash ambulances with DXM independent suspension.

[28] On 18 July 2011 Navistar Defense received a delivery order for an additional 140 MRVs with rocket-propelled grenade (RPG) nets from the U.S. Marine Corps Systems Command.
