This well-designed Miller Industries heavy-duty wrecker attachment is used to tow a semi tractor backwards by the towed vehicle's 5th wheel.
This popular attachment is particularly useful in towing late-model tractors with modern suspension systems that are difficult to hook up without causing damage, or requiring extensive modification for tow. An example is the 2020+ Kenworth Airglide 8 Bag Suspension.
