Built on a Ford F-350, a Chevy C3500 or a Chevy K3500 chassis, the Frontline M1 takes Type I ambulance durability to the next level. Frontline uses a full-extruded body consisting of 2x2 box tubing, 0.090” single piece aluminum skins and a roll-cage style 1/4” box tubing frame. And because we’re serious about strength …

  • The Frontline MI ambulance has been professionally crash and drop tested.
  • Every unit is completely built in a ISO 9001:2015 certified factory for consistency.
  • Frontline builds its product on decades of REV Group’s ambulance knowledge.



Frontline trusts Ford and Chevy to get crews to the scene. These names deliver the most-trusted Type I ambulance chassis configurations to deliver a ride that’s as tough as the most dependable trucks on the market.

A tank is more than just the chassis it rides on. It’s an unrelenting hull that protects its crew on the frontline. Mission ready, Frontline builds the toughest, most agile Type I ambulance modules on the most trusted chassis names.

Type I ambulance storage with muscle.

The M1’s exterior compartments are constructed with a flanged design, giving enormous support to the gear you need, while the interior cabinets feature a 3/4” double-laminated plywood design throughout the entire cabinet for superior strength.


CNC machine-cut side skins for precision.

Every cutout made to the module side skin is created using CNC machinery. These cutouts, which incorporate holes for lights, compartments and mounting locations, is made with extreme precision to ensure a seamless, corrosion-resistant design.


Space and safety, never a Frontline premium.

Frontline’s Type I ambulance model features 49” of aisle space — 4” more than the competitor — providing more room to treat patients. In the event of an accident, an emergency latch lets passengers escape even when handles are inoperable.



At Frontline Emergency Vehicles, durability is the standard. So you won’t find another competitively priced Type I ambulance that puts this kind of emphasis on durability, nor charges you a premium for these standards.
