Composite flooring for recreational vehicles

A recreational vehicle comprising a chassis, at least one axle assembly, a vehicle body, and a composite floor, wherein:

• the vehicle body and the composite floor are supported by the chassis;
• the axle assembly is coupled to the chassis and provides motive support and underbody clearance to the chassis;
• the composite floor comprises a skeletal framework, a plurality of foam core inserts, an impact resistant sheet on an interior side of the composite floor, a weather resistant sheet on an exterior side of the composite floor, and a plurality of contained framework cells;
• the skeletal framework of the composite floor comprises a plurality of closed frame sections defined by frame segments of the skeletal framework;
• each contained framework cell is bounded volumetrically by frame segments of a closed frame section, portions of the impact resistant sheet, and portions of the weather resistant sheet;
• individual ones of the foam core inserts are large enough to frictionally engage at least two parallel frame segments of a closed frame section of the skeletal framework;
• each contained framework cell is packed with one or more of the foam core inserts and the foam core inserts within each cell collectively occupy a substantial entirety of the contained framework cell;
• and
• the skeletal framework, the foam core inserts, the impact resistant sheet, and the weather-resistant sheet comprise a structurally integrated composite floor, such that a collective modulus of elasticity (MOE) of the composite floor comprises modulus components that are attributable to the skeletal framework, the foam core inserts, the impact resistant sheet, and the weather resistant sheet.
