SUMMIT HAULER DIFFERENCE
What Makes a Summit Hauler Different?
The “Soft Touch” Quiet Cab
Standard medium-duty trucks have plastic walls that echo road noise. Summit Hauler strips the interior and installs sound-deadening insulation, covered by unmatched ‘Soft Touch’ walls and headliners. This creates an acoustic environment that allows you to hold a normal conversation at 70 MPH.
The Heavy-Duty Hauler Bed
While other conversions use fiberglass or composite beds that are prone to scratching, Summit Hauler utilizes a heavy-gauge aluminum body with diamond-plate decking. It is designed to be used.
- Integrated Storage: Weather-sealed toolboxes built directly into the bed.
- Versatile Hitching: A recessed trough that accommodates both Gooseneck and 5th Wheel hitches without limiting turning radius.
Safety First (Detroit Assurance)
Summit Haulers are often spec’d with the latest Detroit Assurance 5.0 safety suite, bringing passenger-car safety to a heavy truck. Features often include Adaptive Cruise Control, Lane Departure Warning, and Active Brake Assist—innovations that keep you safe on cross-country trips.

Frequently Asked Questions
Generally, no. Most Summit Hauler M2 106 builds are de-rated to a 19,500 lbs GVWR. This keeps them under the 26,000 lbs federal CDL limit, meaning you can drive them with a standard Class C license in most states (always check your local regulations).
This is a common debate. Summit Hauler focuses heavily on aftermarket sound deadening and “soft walls,” which many owners claim reduces high-pitch wind noise better than the standard OEM interior found in other conversions.
Yes. The Summit bed features a deep trough and a versatile hitch system (often a B&W Turnover ball or air-ride hitch) that easily accepts 5th wheel kingpins or gooseneck adapters.
Summit Haulers are produced by Transwest, a major Freightliner dealer network. This gives owners the advantage of a large support network for parts and service.
