Measuring approximately 24 feet 1 inch in length, it is built on a Ford E-Series chassis and powered by a 7.3L V8 engine, offering a balance of power and efficiency. The exterior showcases a one-piece fiberglass front cap, rotocast storage compartments, and a 15-foot power awning, enhancing both durability and outdoor living space. With a GVWR of 12,500 lbs and a towing capacity of 8,000 lbs, the LC21 is well-suited for various travel needs. 

Inside, the Quantum LC21 offers a thoughtfully designed floor plan that maximizes space and functionality.

The leatherette dream dinette serves as both a dining area and an extra sleeping space. The kitchen is equipped with a three-burner gas cooktop, convection microwave oven, and a double-door refrigerator, allowing for convenient meal preparation. The rear corner bathroom includes a shower, toilet, and sink, ensuring all the comforts of home are available on the road.
