The MK27/MK28 Extra Long Wheel Base Cargo variant of the MTVR family will replace the M814, M927, M927A1, M928 and the M928A1. These trucks use state of the art commercial technology including an independent suspension system, electronically controlled engine and transmission and a central tire inflation system, which increases the off-road maneuverability and mobility of the vehicle. The difference between the MK27 and MK28 is that the MK28 has a 20,000-pound capacity self-recovery winch. The MK27/MK28 is a 7-ton, 6x6 designed for use on all types of roads, highways and cross-country terrain. It is capable of traversing a 60 percent gradient, a 30 percent side slope up to 15 mph and a 40 percent side slope at 5 mph. It is capable of an on-road cruising range of 300 miles. The MK27/MK28 variants are capable of being transported by highway, rail, sea and air. MK27A1/MK28A1 is referred to as “ready to accept armor” (RTAA). This model has upgraded cab mounts, armored flooring, upgraded suspension, and air conditioning. RTAA is not considered an armored vehicle and is interchangeable with the MK27/MK28 to satisfy (T/E) allowances.
