You sound like you are happy with your new truck and it's extended warranty, that is great and I wish you luck with both. I think they bring "Peace of mind" to the new and use vehicle owner, weather they cover the right items or not. I have only had one experiance with extended warrantys and that was about fifteen years ago. We purchased a warranty on a vehical for about 4-500 dollars. Used it for the replacement of a starter and ignition switch that went bad. In our case the warranty was a wash, the cost of the repairs was about the same as the cost of the warranty, so nothing gained and really nothing lost. I have not taken out another extended warranty since, and so far have not needed one. The Dodge warranty seems to pretty comprehensive, and the extended warranty the dealer had seemed to very, very limited in what it covered. Basicly anything that failed because of "Normal wear" was excluded. Isn't all or most failures caused by wear? And wouldn't that make them "Normal"? Even the door hinges weren't covered, or the problems they could cause, because they were "Normal wear" items.
I suppose if it gives someone the extra peace of mind knowing that they have a extended warranty which may cover some future problems, when maybe it is a good ideal for that person. Each to their own, for everybody moves to a different beat.
