The soil of the site should be firm and well drained. In areas where the soil will not support the trailer, use planks or other
suitable material as dunnage. The selected site must provide for access to the unit by towing.
2-11. SHELTER REQUIREMENTS. The trailer requires no sheltering during movement or operation. However, when
parked for long periods of time, consideration should be given to sheltering the unit from extreme sunlight, humidity,
blowing sand, etc., which can be detrimental to the tires, paint, and metal portions of the trailer. For operator/crew and
organizational maintenance, no shelter provisions are required. For direct support maintenance, normal automotive
repair facilities must be provided. Maintenance of the trailer will require a work space of approximately 24 feet by 30
feet.
