Detailed Information
We are a team of engineers and manufacturing specialists with extensive experience in the development, production launch, and quality control of fiberglass vehicles and components for both road and rail applications.
For many years, we have worked closely with trusted manufacturing partners that produce fiberglass and metal components for RVs, trams, trains, buses, ambulances, and other specialty vehicles.
Outranger began with a simple idea: to create a camper trailer for both paved roads and more demanding terrain—and engineer it with the same level of care expected from a modern vehicle.
That approach shaped every part of the design. Materials, components, and construction methods were selected to withstand vibration, moisture, temperature changes, and years of outdoor exposure. The result is a camper designed to maintain its structure, appearance, and functionality long after the first trip.
Durability was only part of the goal. Every detail was also developed around practical use, thoughtful functionality, and a clean, distinctive design.
The Outranger body is assembled from six composite panels. Concealed interior partitions and structural surfaces are made from durable polymer materials.
The rear galley is constructed entirely from fiberglass and finished with a protective polyurethane coating, while the countertop is made from HDPE.
Inside the cabin, molded panels with a polyurethane finish are combined with soft upholstered panels made from polymer substrates wrapped in automotive-grade fabric.
All materials were selected to minimize wear, simplify cleaning, and maintain their appearance and functionality through long-term use.
The cabin features entry doors on both sides of the trailer. A large front window can be opened for additional ventilation, while a roof-mounted ventilation fan provides continuous cabin airflow.
A memory foam mattress is also included as standard equipment.
Four standard exterior colors are available directly through the configurator. An optional custom-color finish is also available for customers who would like to personalize their trailer.
Custom colors are selected using the RAL CLASSIC color system. For the most accurate color selection, we recommend using a physical RAL CLASSIC fan deck, especially when attempting to coordinate the trailer color with a tow vehicle. Colors displayed on a computer or phone screen should be used only as a general reference.
Because each batch of colored gelcoat is produced specifically for manufacturing, the finished shade may vary slightly from the RAL reference. Minor variations may also occur between different production batches, including among our four standard colors.
Not every color in the RAL CLASSIC catalog is suitable for gelcoat production. After you provide your preferred RAL code, we will confirm its availability with our gelcoat supplier. Final approval is provided after the gelcoat has been received by our fiberglass manufacturer and the first physical samples have been produced. If the selected color cannot be used, we will help you choose a suitable alternative.
Customers selecting a custom color will have additional time beyond the standard 10-day preorder period to complete the color-selection process. Custom gelcoat production may also extend the standard production timeline, and any adjusted completion date will be confirmed in your order documents.
In its standard configuration, the rear galley is supplied without a propane cooktop or built-in water system. This setup is ideal for owners who prefer to use portable equipment, such as a portable stove and water container, or who plan to install their own custom equipment.
The optional Dometic D20 cooktop includes a complete propane system powered by a 10 lb propane tank. The optional water system includes a 13-gallon fresh water tank, gravity-fed faucet, sink, and 7-gallon gray water tank. Gray water drains through a standard RV dump connection, which can also be connected to a portable waste tank for additional capacity while camping.
Because the water system is gravity-fed and designed to drain without a pump or pressurized plumbing, it does not require a traditional winterization process. Before winter storage, simply drain all water from the system.
An optional 20-liter Vitrifrigo drawer refrigerator can be installed directly in the rear galley. A second 30-liter Vitrifrigo drawer refrigerator is also available behind the exterior fold-down table.
Located on the right side of the trailer, the fold-down table extends the galley with an additional 48 × 21-inch cooking and preparation surface. It opens and closes in seconds when extra workspace is needed.
The tongue storage box also includes an exterior platform for an additional weather-resistant refrigerator or cooler, with a dedicated 12V outlet provided nearby.
The standard aluminum tongue box provides 9 cubic feet of enclosed internal volume, measured before accounting for the space occupied by the installed battery or battery bank.
An optional aluminum roof rack includes four crossbars for securing cargo and outdoor equipment. A gear-mounting panel on the left side of the body provides M8 mounting points for water containers, storage boxes, recovery gear, and other accessories. Equipment can be installed using custom brackets or mounting solutions available from Motsmann Engineering.
An optional full-size spare wheel is supplied with a dedicated spare tire basket mounted on the tongue.
An optional 2-inch hitch receiver is also available beneath the rear bumper for compatible cargo and accessory carriers.
An optional Kammok 7 ft Crosswing awning can be installed on either side of the trailer. When the optional roof rack is selected, the awning mounts directly to the rack. Without the roof rack, it is installed using a dedicated mounting bracket.
We generally recommend installing the awning on the right side of the trailer and leaving the left side available for a portable shower or privacy tent.
Shower tents are not supplied with the trailer, since many different sizes and configurations are available and owners typically select one based on their individual needs. However, optional mounting brackets are available for securing compatible tents and related equipment to the trailer.
The Outranger body is mounted on a bolted chassis constructed from 3 mm galvanized steel. The modular bolted design simplifies repairs and allows individual chassis components to be replaced or upgraded when needed.
The chassis was engineered specifically around the Timbren Axle-Less independent suspension system and incorporates dedicated reinforced mounting subframes.
Standard running gear includes 30-inch Falken Wildpeak tires mounted on 15-inch wheels. Electric trailer brakes are available as an option.
Optional rear stabilizer jacks can be added to provide additional stability while the trailer is parked.
A 2-inch ball coupler is included as standard equipment, with an optional upgrade to a Max Coupler articulating hitch.
The standard 12V electrical system is powered by a 200Ah Renogy self-heating LiFePO₄ battery and supplies the lighting and all installed onboard equipment.
Interior and galley lighting uses marine-grade LED fixtures from Osculati®. Marine-grade Scanstrut® USB charging ports are installed throughout the trailer for convenient device charging.
Battery and Shore-Power Charging
The standard 200Ah battery bank can be expanded to 400Ah or 600Ah.
Shore-power charging is provided by Victron battery chargers, with charging capacity matched to the selected battery bank:
- 200Ah battery bank — 25A charging
- 400Ah battery bank — 50A charging
- 600Ah battery bank — 75A charging
An optional Fast Charging package adds an additional 25A of charging capacity to any battery configuration.
Depending on the installed charging capacity, the trailer is supplied with either a standard NEMA 5-15P shore-power plug or a 30-amp NEMA L5-30P locking shore-power plug.
Solar Charging
The optional solar charging package includes a 200W Renogy solar panel and a Victron MPPT solar charge controller.
Tow-Vehicle Charging
The optional tow-vehicle charging system uses an 18A Victron DC-to-DC charger. It can connect to the tow vehicle through the standard 7-pin trailer connector or a dedicated Anderson connector.
120V Power
The optional 120V power system is built around a 2,000W Xantrex PROwatt SW2000 pure sine wave inverter. It provides two 120V outlets located in the cabin and rear galley.
Standards and Components
The electrical system is designed and installed in accordance with the applicable requirements of NFPA 1192 and NEC Article 551.
All components used throughout the electrical system are selected from established manufacturers and carry an applicable UL mark.
Propane Heater
The optional Propex HS2000 propane heater provides thermostatically controlled cabin heating. The desired temperature is set using a dedicated controller, and the heater automatically cycles to maintain it.
The heater option includes a complete propane system powered by a 10 lb propane tank.
Air Conditioning
The optional air-conditioning system is built around the portable ZERO BREEZE Mark 3, securely integrated inside the cabin. Factory-installed air ducts route airflow through the roof, while condensation drains either into the gray water tank or directly outside, depending on the selected configuration.
The unit is powered directly from the trailer's battery bank through a dedicated 48V power system.
An A/C Ready package is also available. It includes factory-installed air ducts, drainage, 48V power, and the required mounting bracket, allowing an owner to purchase and install a ZERO BREEZE Mark 3 later.
If you plan to use the air conditioner frequently, we recommend selecting a battery bank of at least 400Ah.
The lower section of the body, which receives the greatest exposure to road debris and surface wear, is protected with a matte black Raptor polyurethane coating. The exterior fold-down table and gear-mounting panel use the same durable finish.
Minor scratches and chips in the Raptor coating are relatively easy to repair. Raptor touch-up products and repair kits are available, and the coating's original orange-peel texture can be recreated by applying the material with a textured roller. This allows many small repairs to be completed at home without refinishing an entire panel.
The remaining glossy exterior surfaces are finished in polished gelcoat. Fiberglass with a gelcoat finish is widely valued for its durability, wear resistance, and ability to withstand long-term outdoor exposure. If light scratches, scuffs, or surface oxidation occur, they can typically be corrected using standard gelcoat polishing and restoration methods.
More significant fiberglass damage can be repaired using standard composite and gelcoat repair methods.
Our gelcoat colors correspond to standard RAL color references. The specific RAL color code used for each trailer is recorded and linked to its serial number, making it easier to identify and order matching gelcoat if the body is ever damaged and a repair becomes necessary.
We offer component packages for manufacturers and professional builders interested in assembling trailers at their own production facilities. Our components can be used to assemble and sell Outranger trailers or to develop custom trailer models based on our fiberglass body design.
Available components may include fiberglass body assemblies with full or partial interior integration, chassis frames, roof racks, exterior storage compartments, and other Motsmann Engineering components.
Depending on the project, trailers may be assembled with VINs assigned by Motsmann Engineering and in accordance with our assembly instructions. Manufacturers may also use our components to produce and sell their own customized trailers under their own brand and VIN.
Component packages include applicable drawings, technical documentation, and assembly instructions. We also provide technical consultation on electrical, plumbing, and propane systems to help manufacturers meet applicable code and safety requirements.
Third-party equipment is not included. Electrical and electronic systems, appliances, suspension components, wheels, brakes, windows, lighting, and similar equipment must be sourced separately by the purchaser.
Any completed trailer using our body components must be assembled in accordance with all applicable federal, state, and local requirements, including applicable provisions of DOT regulations, NFPA 1192, and NEC Article 551.
Component packages are available for wholesale orders of 10 or more units. Package contents, customization, branding, technical support, production responsibilities, and delivery terms are established individually for each project.
