Setting Up Your 5th Wheel
Proper setup is crucial! This section details hitching, unhitching, leveling, stabilizing, and connecting essential utilities for a secure and comfortable experience.
Hitching and Unhitching Procedures

Safety First! Before hitching, ensure the towing vehicle is on level ground and the fifth wheel landing gear is fully raised. Carefully align the king pin with the fifth wheel hitch jaw.

Slowly drive the truck forward until the king pin is securely seated in the hitch. Verify proper locking with the jaw handle. Lower the front landing gear until it just contacts the ground, then double-check all connections – safety chains, electrical, and emergency brake lines.
For unhitching, raise the fifth wheel slightly with the landing gear before releasing the hitch jaw. Slowly back the truck away. Fully lower the landing gear to support the unit; Disconnect all utilities and safety connections before moving the truck.
Always consult the hitch manufacturer’s instructions for specific procedures and weight ratings.
Leveling and Stabilizing the Unit
Achieving Stability: After hitching, leveling is crucial for comfortable living. Utilize leveling blocks under the tires to achieve a side-to-side and front-to-back level position. A bubble level placed inside the 5th wheel confirms accuracy.
Once level, deploy the stabilizer jacks at each corner. These jacks do not lift the unit; they provide stability, minimizing rocking and movement. Extend them until they firmly contact the ground, but avoid over-tightening.
Regularly check the level during your stay, as settling can occur. Proper leveling ensures doors and appliances function correctly and enhances overall comfort. Avoid using leveling jacks for significant lifting – use appropriate leveling blocks instead.
Connecting Utilities (Water, Electric, Sewer)
Essential Connections: Begin with the freshwater hose, connecting it to the city water inlet. Ensure a potable water source and use a water pressure regulator to protect the plumbing system. Next, connect the 30 or 50 amp electrical cord to the campground pedestal, verifying proper voltage.
For sewer connection, use a sewer hose and secure it properly to both the RV outlet and the campground sewer connection. Always use a clear elbow fitting to monitor tank drainage.
Double-check all connections for tightness before use. Proper utility connections are vital for safe and comfortable operation of your 1999 Fleetwood Avion 5th Wheel.
