Problem: Vehicle description: motor homes built on a roadmaster chassis. Inadequate bracing was used to secure the fuel tank. The brace could fail allowing one end of the fuel tank to loosen from its position and hang lower than the other end.
Risk: The fuel tank could eventually separate from the vehicle and drop to the ground, increasing the risk of personal injury or a vehicle crash.
Fix: Dealers will install an additional brace under the fuel tank.

Problem: On certain motor homes, the psi recorded on the federal certification label is incorrect. The initial label shows psi as 90 lbs front and 100 rear. The correct information should be a psi of 105 front and 115 rear.
Risk: These vehicles do not comply with the regulations.
Fix: Dealers will install a corrected label on these motor homes. Owner notification began on April 28, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free label within a reasonable time should contact Monaco at 1-877-466-8226.

Problem: On certain motorhomes, fifth wheels and travel trailers equipped with norcold refrigerator cooling units model numbers 1200lr and 1200rim, these refrigerators can experience low cycle fatigue failure which can lead to the liquid solution slowly leaking from the sealed, pressurized cooling unit through a small crack.
Risk: If a leak occurs and the unit is continually operated, hydrogen gas may be expelled and can be ignited, resulting in a fire, possibly causing serious injury or death.
Fix: Norcold will notify its customers and provide a replacement cooling unit free of charge. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact norcold service center at 1-800-667-3005 or Monaco at 574-862-7211.
