From a previous post...
I purchased my unit in July 2007 and declined at the dealership for the third party extended warranty. I think the third party warranty was $1000 - $2000 and extended the warranty from up to 3 to 7 years. The dealer gave me a big envelope full of all of the installed manufacturer items and a lot of the manufacturers offered their own extended warranties.
I opted for these extra coverages as it was overall less expensive.
Forest River itself had an additional 12 month warranty $150.00 U.S.
which covered Suspension System & Axles, Frame, Floor, Refrigerator, Power Converter, Range, Interior Cabinet Frame Face & Sides, Windows, Water Heater, Water Pump, TV Antenna, Furnace, Awning, Microwave, Steps, LP Tanks, Tires, Exterior Entrance Door, Jacks, Roof Membrane, Slide Out Mechanism, Toilet, Air Conditioner, Furniture, Valances, Mattress, Stereo & Speakers. Listed above is all covered for 2-years from my date of purchase with exception to what is listed below.
Dometic offered 3+3 warranty on the Air Conditioner providing an extra 3 years on top of its original warranty for $130.00 to which my coverage now expires in 2013.
Suburban offered an extended warranty on its furnace to which I can not remember the cost but it was super cheap (I think $50.00 or so) and it extended the warranty until 2014.
I went through all the manufacturer documents that came with the unit and made a database in my computer listing all products and their warranty expiry dates. I also made copies of the payments that I sent in for any additional coverages.
