Imperial Outdoors Sport S145: 4-Season Capability, Built for the Road Less Traveled

The Imperial Outdoors Sport S145 is engineered for adventurers who want real off-road confidence without giving up the comforts that make longer trips enjoyable. A rugged steel chassis paired with Cruisemaster® CRS independent suspension, 31" all-terrain tires, and up to 18" ground clearance creates a capable platform for rough forest roads, while the Cruisemaster® DO35 articulating hitch adds stability and peace of mind when conditions get unpredictable.

Inside, the S145 delivers comfortable simplicity with a clean, contemporary design, real-wood cabinetry, and a smart layout that sleeps 2+ with a convertible full bed/dinette. A full dry bathroom with a separate shower brings true convenience to off-grid travel.

Built for serious 4-season use, the Sport series features fully insulated wall panels and heated tanks to keep systems functional in freezing conditions, while summer comfort is handled by a 12V air conditioner that can operate without shore power. With 240W rooftop solar and 204Ah of lithium battery storage, you can reduce plug-in time and stay out longer.
