This is why I don't recommend extended coverage past the FR 2nd year warranty for campers.
Almost NOTHING is actually covered. Most items that would fail have their own individual warranty that exceeds the 1 year of the basic unit. For example the roof material is warranted for 10 years.
Additionally they will not cover anything that is even remotely YOUR fault.
Leaks for example are not covered under warranty since you need to check your roof every 30 minutes or so with a Dicor gun in your hand according to the underwriter. They are very creative about blaming you for poorly designed stuff that breaks.
