In 2003 we bought a brand new class A that had a 3 year manufacturers warranty. Every thing was covered. They sold us an extended warranty that we weretold would take effect when our 3 years was up. The extend warranty was for 7 years. So we thought that we were covered till 2013. But not true we recently found out. It started the day we bought the class A. So we paid for three years of duplicate coverage and never had to use the extended.
We won't do that again.
