What is a "fifth wheel"?

A fifth wheel is a type of trailer that attaches to the bed of a truck using a special connector, allowing it to be easily pulled while providing living space for travel or camping. It typically has areas for sleeping, cooking, and sometimes a bathroom, offering the comforts of home while on the road. Fifth wheels are popular for long trips or camping, as they provide more space and stability than regular travel trailers. These trailers are larger and offer more features, making them suitable for those who want more comfort while traveling.
