Length
38'10"
Fuel Type
diesel

Although more expensive upfront, diesel engines are preferred by those who require more pulling power (torque), greater efficiency, and longer engine life than their gas-powered counterparts.

Built on a Freightliner chassis and powered by a Cummins® 6.7L 340-hp, 700 lb-ft torque engine, these models are available with up to 2 slide-out rooms and benefit from a flat floor throughout.

SuperStructure Construction

Our exclusive steel SuperStructure® construction surrounds the cab with a strong, durable support system that delivers industry-leading safety and security.

Thermo-Panel Walls

Our trademark Thermo-Panel® wall construction sandwiches the welded aluminum framework, air ducts and insulation between the interior and exterior walls to create strong, durable, and lightweight sidewalls.

Interlocking Joints

Specially designed interlocking joints evenly distribute the weight of the roof along the entire span of the walls, making our empty shell so strong it doesn’t need internal reinforcement.

Laser-Cut Tubing

Our precision laser cutters create precise joints in structural steel that require less welding that typical butt joints, making them far stronger.

Automotive-Grade Wiring

We follow automotive standards for secure and reliable connections. Wires are clearly labeled for easy identification, then crimped and spliced using an advanced solderless welding process and heat-shrink covering.

All-Electric Zero Emission

Our groundbreaking 100% Battery Electric Vehicle is ideal for short-range applications, particularly those involving sensitive equipment or environments. Qualifies for many government purchase and infrastructure incentives.

E-Coating

Critical steel structural components go through a multi-stage full immersion electrocoating system that charges each part with an electrical charge to attract the protective coating, causing it to be “plated” onto the part in a uniform thickness.

Commercial-Grade Floor

We use 1-1/8" commercial-grade plywood to provide a solid walking surface as well as added flexibility when it comes to mounting equipment.

Chassis

Features
1 1/8" Wood Flooring

Commercial grade floor for solid walking surfaces and flexibility in mounting equipment.

Thermo-Panel® Sidewalls

By layering fiberglass and high-density block foam insulation with welded aluminum support structures, we create some of the industry’s strongest, most durable and lightweight sidewalls.

Laser-Cut Tubing

Precision laser cutters create precise joints in structural steel that are stronger and require less welding.

Interlocking Joints

Specially engineered interlocking joints connect the floor, sidewalls and roof where competitors often rely on simple screws to bear the weight.

Solid Framework

Aluminum extruded in our own facility to our exacting standards creates an extremely strong and solid structural framework.

Fiberglass Roof

The crowned, one-piece fiberglass roof is backed by a 10-year limited parts-and-labor roof skin warranty.

E-Coating

An electrodeposition coating helps protect critical steel components.

Embedded Steel

Metal substructures embedded into the sidewall provide solid attachment points to keep cabinets and appliances mounted securely in place.
