How are you tieing down your car in your enclosed trailer

For the record.....
Safety chains must be crossed

PENNSYLVANIA
Whenever 2 vehicles are connected by a ball-and-socket type hitch, or pintle hook without a locking device, they must also be connected by 2 safety chains of equal length, each safety chain having an ultimate strength at least equal to the gross weight of the towed vehicles. The safety chains must be crossed and connected to the towed and towing vehicle and to the towbar to prevent the towbar from dropping to the ground in the event the towbar fails or becomes disconnected. The safety chains must have no more slack than is necessary to permit proper turning.
