I am buying a NEW unit

and have been offered a RV Protection Plan. Supposed to cover everything but fuels, bulbs, etc. Does anyone have any experience with these types of insurance. The company is a large USA insurance type. Quite a bit of cash $10k, but 7 years of coverage. The $10k would go a long way toward repairs and manufacturers have their own warranty's. Any comments from positive and negative experiences??? Thanks in advance. Unit is a 2013 Tiffin, 40ft., Cummins 380, etc
