What must be done with the M915 mudflaps when towing a M969 trailer?

Answer: A — Remove and stow

When towing a M969 trailer with an M915, it is necessary to remove and stow the mudflaps. This action is crucial to prevent damage to the mudflaps and ensure they do not interfere with the operation of the trailer. The trailer could potentially block the mudflaps or cause them to become a hazard on the road. By removing them, you eliminate the risk of them dragging on the ground or getting caught in moving parts, which could lead to safety issues while towing. Proper stowage is important to keep the mudflaps safe and ready for reinstallation when not towing the trailer.
