OUTBACK OB120 The Imperial Outdoors Outback OB120 is the most compact and versatile trailer in the Imperial Outdoors lineup — a purpose-built, go-anywhere adventure basecamp designed for the adventurer who refuses to let trailer size determine where they can go. With a dry weight of 2,543 lbs and a GVWR of 4,200 lbs, the OB120 is engineered to pair with a wide range of vehicles — Jeeps, mid-size trucks, and capable SUVs — making it the most accessible Imperial Outdoors trailer to own and tow without any vehicle upgrades.

Don't let the compact footprint fool you. The OB120 is built on a rugged powder-coated steel chassis with Cruisemaster CRS coil spring independent suspension, electric drum brakes, 32" all-terrain tires, and 16.5 inches of ground clearance to the skid plate. A DO35 articulating hitch allows the trailer to swivel, pivot, and rotate independently from the tow vehicle for a more stable and controlled towing experience on rough backcountry terrain. Its low center of gravity and compact dimensions let it thread tight trails and navigate technical terrain that would stop a full-size trailer cold.

Four-season performance is standard. Nearly 3 inches of composite insulation, thermally broken windows, and heated water tanks keep the OB120 functional in extreme temperatures, with the cabin and systems engineered to perform down to -40°F. This cold-weather capability is no accident — it's the direct result of Imperial Outdoors' roots in building ice fishing structures designed to survive Wisconsin winters, applied to the most compact trailer in the lineup.

Off-grid capability is available and fully customizable. With available rooftop solar, a 324Ah lithium battery system, and a 12V rooftop air conditioner, the OB120 can be configured for true long-term energy independence. Heated water tanks keep the system functional in freezing temperatures, and the modular power system allows owners to start simple and upgrade as their adventure ambitions grow.

Where the OB120 truly shines is in its outdoor living design. A slide-out outdoor kitchen with a 75L fridge/freezer turns any campsite into a fully functional basecamp, while the thoughtfully designed compact interior maximizes every inch of available space for sleeping and storage. An available 360° awning expands the living space dramatically and provides shade and shelter in any conditions. The OB120 isn't just a trailer — it's a platform for adventure, built to be configured, customized, and taken anywhere your rig can go.

SPORT SERIES S145 The Imperial Outdoors Sport Series S145 is a rugged, trail-ready four-season adventure trailer built for the adventurer who wants serious off-road capability and genuine off-grid comfort in a package that's accessible, versatile, and built to last. At 20 feet 7 inches long with a dry weight of approximately 3,900 lbs, the S145 is the lighter, more nimble of the two Sport Series models, designed to pair with a wide range of capable half-ton trucks and larger SUVs without requiring a heavy-duty tow vehicle upgrade.

The S145 is built on a reinforced, powder-coated steel perimeter frame with Cruisemaster CRS coil spring independent suspension and electric drum brakes, a trail-proven platform that delivers a smooth, controlled ride on rough backcountry roads that far exceeds what a standard trailer suspension can offer. Paired with 31" all-terrain tires, 21 inches of ground clearance, and a DO35 articulating hitch that allows the trailer to swivel, pivot, and rotate independently from the tow vehicle, the S145 handles challenging terrain with confidence and composure.

Four-season capability is built in from the ground up. Nearly 3 inches of fully insulated composite wall panels, thermally broken acrylic windows, heated water tanks, and an enclosed and heated underbelly keep everything functional well below freezing. A Truma Combi furnace and water heater maintains interior comfort down to -40°F, and the 12V air conditioner keeps the cabin cool in summer heat, running entirely on battery power without shore power.

Off-grid capability comes standard. The S145 includes 240W of rooftop solar and lithium battery storage as standard equipment, with available upgrades for those who want to push further and stay longer. A 12V air conditioner, 60-gallon fresh and grey water tanks, and heated water tanks give the S145 the self-sufficiency to stay out well beyond a typical weekend trip without planning around the next hookup.

Inside, the S145 delivers a level of comfort that surprises first-time buyers. Real-wood cabinetry, a fully appointed kitchen, a full dry bath with separate shower, and a thoughtfully designed living space make the S145 a genuine home base for extended adventures. It's a trailer that proves you don't need to spend more or tow more to live well in the backcountry.
