The floating substructure will be separated from the lateral frame extensions with neoprene elastomer isolators. These isolators will reduce the natural flex stress of the chassis from being transmitted to the body. The isolators will have a broad load range, proven viability in vehicular applications, be of a fail safe design and allow for all necessary movement in three (3) transitional and rotational modes. The neoprene isolators will be installed in a modified V three (3)-point mounting pattern to reduce the natural flex of the chassis being transmitted to the body. 4GGRESSIVE WALKING SURFACE q11 exterior surfaces designated as stepping, standing, and walking areas will comply with the required average slip resistance of the current NFPA standards. LOUVERS All body compartments will have a minimum of one (1) set of automotive style, dust resistant louvers pressed into a wall to provide one way airflow out of the compartment that prevents water and dirt from gaining access to the compartment. TESTING OF BODY DESIGN Body structural analysis will be fully tested. Proven engineering and test techniques such as finite element analysis, model analysis, and strain gauging have been performed with special attention given to fatigue, life and structural integrity of the body and substructure. The body will be tested while loaded to its greatest in-service weight. The criteria used during the testing procedure will include: - Raising opposite corners of the vehicle tires 9.00" to simulate the twisting a truck may experience when driving over a curb. - Making a 90 degree turn, while driving at 20 mph to simulate aggressive driving conditions. - Driving the vehicle on at 35 mph on a washboard road. - Driving the vehicle at 55 mph on a smooth road. - Accelerating the vehicle fully, until reaching the approximate speed of 45 mph on rough pavement. Evidence of the actual testing techniques will be made available upon request. LEFT SIDE COMPARTMENTATION A full height, roll -up door compartment ahead of the rear wheels will be provided. The interior dimensions of this compartment will be 62.00" wide x 61.50" high x 26.00" deep in the lower 54.50" of the compartment and-1-163" deep in the remaining upper portion behind the roll -up door. The depth of the compartment will be calculated with the compartment door closed. The compartment interior will be fully open from the compartment ceiling to the compartment floor and designed so that no permanent dividers are required between the gpper and lower sections. The clear door opening of this compartment wiU be',AQ_,.0W Wide x 54.50" high.
