2010 Winnebago 40L. . .from Hell !

Video tape every thing and then use a digital camera to create a photo file. Write a well reasoned letter and in your best English and grammar make your specific request known. If it were me I would ask for the full purchase price back based on MSRP. If they call to tell your the repairs are complete very calmly tell them you request all communication be in writing. Record all conversations. Reiterate you request that what ever you requested in your letter be granted. If you weaken and decide to take it back test every system several times in the dealers lot. You preform the test and do let the dealer employees preform the test. If any system fails do not take it and in writing make you demands again known. Be polite, calm and very specific as to the issues and the demands you have.

If all else fails post your video to you tube, contact your local TV consumer reports, and even send the video to the major networks.
