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 those used for transporting light loads or recreational vehicles. Single-axle setups are generally lighter and easier to maneuver compared to multi-axle configurations. Single-axle vehicles are often used in applications like utility trailers and camping trailers. They provide a balance between capacity and ease of use, making them suitable for personal and light commercial purposes. However, they may have limitations in terms of load capacity and stability compared to dual-axle or triple-axle options.
