Identifying Your Specific 1999 Avion Model
Fleetwood Avion produced several 5th wheel models in 1999‚ each with unique floorplans and features. Locating your specific model number is crucial for accurate parts ordering and accessing the correct owner’s manual.
This number is typically found on a sticker located on the trailer’s frame‚ often near the front or on a side wall inside a cabinet. It may also be present in the original documentation.
Referencing this number when searching for PDF manuals online will ensure you obtain the correct information for your unit. Knowing your model allows for targeted troubleshooting and maintenance‚ maximizing your Avion’s longevity.
Understanding the Chassis and Frame
The 1999 Fleetwood Avion’s chassis and frame are fundamental to its structural integrity and safe operation. Understanding their components is vital for proper maintenance. The chassis‚ comprising springs‚ wheels‚ tires‚ axles‚ and the frame itself‚ is engineered to support a specific maximum load.
This load includes the trailer’s weight plus cargo. Exceeding this capacity compromises handling and can cause structural damage. Regularly inspect the frame for signs of rust‚ cracks‚ or bending. Tire pressure and wheel bearing lubrication are critical for safe towing.
Proper weight distribution is also essential for stability; consult your owner’s manual for guidance.
Weight Distribution and Capacity
Proper weight distribution is paramount for safe and controlled towing of your 1999 Fleetwood Avion 5th wheel. Aim for approximately 10-15% of the total trailer weight to be supported by the king pin. Uneven distribution leads to sway and diminished braking performance.
The Gross Vehicle Weight Rating (GVWR) – the maximum permissible weight – is crucial. This figure‚ found on the trailer’s data plate‚ must not be exceeded. Carefully calculate the weight of all cargo‚ including water and propane‚ before each trip.

Overloading stresses the chassis and tires‚ increasing the risk of failure. Consult your owner’s manual for specific weight limits and distribution guidelines.
Electrical System Overview
Your 1999 Fleetwood Avion 5th wheel utilizes both 120V AC and 12V DC electrical systems. The 120V system powers appliances when connected to shore power‚ requiring appropriate adapters and surge protection. Circuit breakers protect against overloads; familiarize yourself with their location and function.
The 12V DC system‚ fueled by a battery (or batteries)‚ operates lights‚ the water pump‚ and potentially the furnace fan. Regular battery maintenance – checking water levels (if applicable) and terminal cleanliness – is vital.
A converter transforms 120V AC to 12V DC‚ charging the battery when shore power is available. Consult your manual for specific wiring diagrams and component locations.
120V AC Electrical System

The 1999 Fleetwood Avion’s 120V AC system provides power for standard household appliances when connected to an external power source – shore power. Always use appropriately rated extension cords and adapters‚ and consider a surge protector to safeguard sensitive electronics.
The electrical panel houses circuit breakers‚ protecting individual circuits from overloads. Never replace a breaker with one of a higher amperage. Identify each breaker’s corresponding appliance or outlet.
Inspect wiring for damage before each use. Refer to your manual for the system’s wiring diagram and maximum amperage draw. Proper grounding is crucial for safety.
12V DC Electrical System & Battery Maintenance
The 12V DC system in your 1999 Fleetwood Avion powers lights‚ the water pump‚ and potentially the furnace fan. This system relies on one or more deep-cycle batteries‚ crucial for off-grid operation. Regularly check battery terminals for corrosion and clean as needed.
Maintain proper electrolyte levels in flooded lead-acid batteries (if applicable) with distilled water only. Periodically test battery voltage with a multimeter; a fully charged battery should read around 12.6V.
Avoid deep discharging‚ as it shortens battery life. Consider a battery maintainer during extended storage. Consult your owner’s manual for specific battery type and charging recommendations.
Plumbing System Guide
Your 1999 Fleetwood Avion’s plumbing system delivers fresh water and manages waste water efficiently. Understanding its components is vital for comfortable travel. The system includes a fresh water tank‚ pump‚ and hot water heater‚ alongside gray and black water holding tanks.
Regularly sanitize the fresh water tank to prevent bacterial growth. Inspect all plumbing connections for leaks before each trip. Proper waste water management is crucial; always use RV-specific toilet paper and tank treatments.
Avoid overfilling tanks and utilize appropriate dump station procedures. Refer to your manual for specific tank capacities and maintenance schedules.
Fresh Water System Operation
The fresh water system in your 1999 Fleetwood Avion provides potable water for all onboard needs. Begin by filling the fresh water tank using the designated city water inlet or a hose. Ensure the tank is adequately supported during filling.
Activate the water pump to pressurize the system. Check faucets and showerheads for leaks. The hot water heater requires both 120V AC and water to operate; follow the appliance section for detailed instructions.
Regularly sanitize the tank with a bleach solution to maintain water quality. Always drain the system before extended storage to prevent freezing and damage.

Waste Water System Management (Black & Gray Tanks)
Proper management of your 1999 Fleetwood Avion’s waste water system is crucial for hygiene and environmental responsibility. The black water tank holds toilet waste‚ while the gray water tank collects water from sinks and showers.
Always use RV-specific toilet paper to prevent clogs. Regularly flush the black tank with plenty of water after each use. Utilize appropriate tank treatments to control odors and aid in breakdown.
Empty both tanks at designated dump stations‚ following all local regulations. Never dump waste into the environment. Ensure proper sealing of the dump valve to prevent leaks and unpleasant smells.
Interior Features and Operation
