The design of the body must be sufficient to withstand the twisting and abnormal flexing, stresses, and other occupational hazards that occur when traveling on unimproved mountainous and rangeland roads. No commercially designed bodies intended for use in other vocations or applications are acceptable in quality, construction, design, or longevity.

5.1.1 The manufacturer shall fabricate the body from galvanneal steel.

5.1.2 The manufacturer shall avoid damaging the hardware or the mounting surface when installing hardware parts, such as hinges, catches, handles, or knobs. After fabrication, the manufacturer shall clean all parts of the following: smudges; loose, spattered, or excess welding; metal chips or filings; or any other foreign material which might detract from the intended operation, function, or appearance of the apparatus or its equipment.

This would include any particles which could loosen or become dislodged during the normal expected life of the equipment. Whenever possible, cleaning shall take place before assembling the parts.

5.1.3 Threaded parts or devices shall show no evidence of cross-threading, mutilation, or detrimental burrs.
