The fifth wheel is a towable that connects to the tow truck directly above the rear axle by way of a special fifth wheel hitch. This causes several feet of the connected trailer to hang over the tow truck, placing about 15 to 25% of the trailer’s weight on the rear axle of the truck.

Commercial semi trucks and trailers use this hitch configuration.

Other terms used for fifth wheel:

• 5th wheel
• Fiver

Sub-Types

The fifth wheel has one sub-type:

Toy Hauler

The term toy hauler is applied to both fifth wheels and travel trailers, and it describes an RV designed to carry toys—small cars, dune buggies, four wheelers, motorcycles, etc.

Distinguishing features of a toy hauler is the large door in the back which opens down to create a ramp, dedicated garage area or fold-away furniture in the main living compartment, and often a third axle to support the heavy toys.

Fifth Wheel Pros

• Easier and safer to tow than travel trailers, but requires more caution and skill than motor homes.

• Spacious, open floor plans suitable for fulltimers.

• Large trailers require large, medium duty trucks.
• Driving and living compartments are separate. Living area inaccessible while moving.
• Generally cannot tow vehicle behind trailer.
• Larger models can be difficult to maneuver in tight spaces.
• On tall models top clearance can be a problem under low branches and structures. Problem compounded if carrying items on roof such as canoes.
