I have the 7 year bumper to bumper extended warranty on my 09 Bighorn 3670 RL. It cost me about $1300.00 Cdn $. It is a marketing plan. Look at it this way, it will eliminate nuisance claims for the insurer. After all, who is going to make a $100.00 claim for something minor and lose their premium refund at the end of the term?! Once again, if you are in the last year of your term and have a $500.00 repair, are you going to claim it and forfeit the $1800.00 refund next year or pay the $500.00 and get your full refund back! On the other hand, if you had a fridge failure or some major breakdown such as an axle or frame repair, the warranty would be worth it. It all depends on how lucky you feel!
