XM1087 Expandable Van

The XM1087 Expandable Van is envisioned to be a mobile office used at various echelons in a field environment. The M1087 van sides pull out from the main body to form the office complex. It is equipped with 110V AC to operate computer, radio and air condition systems. A 24 VDC electrical system is provided to operate the electrical components (radios and blackout lights, etc.) until the office complex can be set up. The vehicle is still in the developmental phase.

  • Full-time all-wheel drive
  • Soldier-smart CTIS (Central Tire Inflation System)
  • Fully automatic transmission
  • Integral transfer case
  • Anti-sway bar
  • High horsepower-to-weight ratio
  • Fully MANPRINT compliant
  • HAEMP hardened
