TXBobcat and all,
Thanks for asking and responding to the tough questions to provoke some critical thinking on a couple serious issues. This indeed has blossomed into a good debate. I love it.
Personally, I don't think there is a right or wrong answer. I think one of the root questions being asked is that of design and workmanship responsibilities.
For instance, does Lippert supply components designed to Heartland's specifications, or does Heartland design a finished product around the standard components that are independently designed and marketed by Lippert. The only clear answer to this question is in the agreements and contracts between the two companies.
Likewise for warranty responsibilities. If Heartland wanted to shorten their warranty "supply chain," they would defer the responsibilities (via their dealer network and customer base) to Lippert directly (Better value, faster, less controversial) or should Heartland add overhead, cost and time delays by warrantying the product themselves and fighting the battles with Lippert after the fact?
The answer in my mind comes down to Heartland's overall marketing and business strategies.
I had a warranty issue with furniture in our 3670. I was immediately referred to Flair by Heartland. At first blush, I was somewhat agitated because I really felt I was entitled a single point of contact and someone to hold accountable. I felt I was being passed off to someone else. I went to Flair (and CC'd Heartland on the communications) and Flair resolved the problem for us. I never received any additional or follow-up communication from Heartland, but the problem was satisfactorily resolved. In retrospect, Heartland would have likely delayed the process and added cost to their business operation, which would be passed on to the future consumers.
The problem was almost assuredly dealt with far more effectively in this manner. Despite knowing that, my "Brand Loyalty" was with Heartland not with their vendors, and I felt somehow let down; an emotional catch-22.
To tie back to the anaolgies of the automotive industry (I think someone pointed this out using the new home/appliance analogy already), GM, Ford, and Chrysler do not warrant the tires on their vehicles. If you have a warranty problem, they will refer you straight to the tire manufacturer's authorized service centers.
Not to be redundant, but the detail is in their marketing/business model, and their agreements with their suppliers.
