A "Single Axle" refers to a type of vehicle or trailer that has only one axle, which is a central shaft that connects two wheels. This design is commonly found in smaller trailers, such as utility trailers or some types of campers. Single axle setups are generally lighter and easier to maneuver compared to their dual axle counterparts. Single axle vehicles typically have a lower load capacity, making them suitable for lighter loads. They are often used for personal or recreational purposes, such as transporting lawn equipment or bicycles. However, they may not provide the same stability as vehicles with multiple axles when carrying heavier loads.
