Why is it called a pig trailer?
Pig trailer: When a trailer has just one axle, it’s defined as a pig trailer. The axle is found in or near the middle of the trailer, holding the weight of the load with two wheels. It has a drawbar connecting it to the towing vehicle. Most caravans, boat trailers and box trailers fall into the pig trailer grouping.
