It's been my observation through about 15 years of being around Keystone RV's, that Keystone tries as hard as the other "people say they're better built" manufacturers... What most people don't realize is that Keystone has no "eyes on your damage" and they are limited to an approval process based SOLELY on what the dealership documents and the photos they submit with the claim.
If they're thorough in their documentation, address the possibilities that if it is not considered to be a warranty issue, and document those reasons why it should be warranty, add facts like what the owner has done to preserve the warranty and then explain why it should be a "manufacturing defect", then almost all the issues are approved for warranty. It's the LAZY dealership warranty writer or the dealership's directive to "minimally document warranty items" that cause the issues... I have consistently seen Keystone "bend over backwards" to help an owner when the dealership steps up to support the claim. On the other hand, I've seen dealerships that "deep six every owner they can" by not being aggressive with documentation and what's put on paper as to WHY it should be a warranty claim...
Why would a dealership do such a dastardly thing ???? Probably several reasons, but my observation is that if the owner pays for the labor, it's $175-250/hour. If Keystone pays, it's $125-150 per hour and sometimes the approved maximum hours are limited such that it's impossible to do the repair work in the allotted time. Keystone won't pay more, so the overtime is a dealership loss. But the dealership can "keep on billing till the cows come home" if the owner is paying the bill.... So, at some dealerships, minimum documentation means more money for the repair.... Sad this happens, but.....
LadyCPA, congratulations. Looks like you found a dealership that's a "keeper"...
