The federal lemon law protects you, the consumer, when a large truck or RV manufacturer fails to uphold their written warranty. However, the manufacturer must be given reasonable time to correct and repair the vehicle, so always take the RV to an authorized dealer so they may attempt to remedy the problem.
Always keep well-organized records regarding the complaints, repairs, and the time the vehicle was out of service. It is also a good idea to keep a record of all correspondence regarding the dealer and the manufacturer.
