Off-Road Capable
Take the road less traveled! A rugged steel chassis, combined with Cruisemaster CRS suspension, 31 inch all-terrain tires and 18 inches of ground clearance provides a capable platform that’s eager for those rough forest roads. The Cruisemaster DO35 articulating hitch ensures safety and peace-of-mind in rough conditions. Let the Sport series bring you further into nature
Rugged Design
Our fully insulated (almost 3” thick) wall panels matched with the Truma Combi furnace/water heater combo set the stage for cold-weather comfort down to -40 ̊. Heated water tanks keep everything functional when the weather gets below freezing outside. The 12V air conditioner keeps you cool during the summer months, even off-grid.
Reduce your plug-in time
With the 3 x 80W solar panels installed on the roof and lithium power storage, you can reduce your time connected to the grid. The 12V air conditioner and refrigerator operate using battery power, reducing the need for an outside power supply. The solar keeps your battery topped up without connecting to shore power.
Rugged Steel Chassis
The Sport Series chassis is rugged and durable, allowing you peace-of-mind when attacking those rough back roads away from civilization. With our signature perimeter frame construction and rigid design, you can rest assured that the S145 will follow you where you want to go, and get there in one piece. When the road gets rough, keep on going!
