When evaluating light duty tow trucks (typically Class 4 or 5), focus on the Gross Vehicle Weight Rating (GVWR), which usually ranges from 10,000 to 19,500 lbs. Ensure the underlift lifting capacity meets your specific recovery needs (commonly 4,000 to 8,000 lbs). Pay close attention to the winch rating; a standard 8,000 lb to 10,000 lb planetary winch is essential for efficiency. Additionally, verify the boom structural integrity, prioritizing high-tensile steel construction for durability and safety during towing operations.
