I did a search on Bing for ISO certified RV manufacturers and that is where I came up with those names. The thing that is most amazing is how you and others seem unwilling to accept that Heartland or Thor are not certified with any agency that would assure better product quality. I would think people who are either potential RV buyers or present owners would embrace anything that would improve the RV industry. No wonder the RV industry is getting reputation of poor quality as long as people don't demand better from them.
The present RV industry reminds me of the auto industry back in the 60/70's that were producing poor quality and many Ford, Chevy, Dodge owners/loyalists kept ignoring it or making excuses that enable that industry to continue with poor quality. It took competition from Japan and others to make long needed changes that improved quality that we see today.
Dave,
You're confusing quality process certification with ecologically sound designs, which is what Green RV certification is about.
You're also confusing quality processes with marketing. The certification is a marketing claim. Certification is not required to have good quality, although one might argue that if you have a certification, you're more likely to have good quality.
Keystone RV on their website makes a number of claims about quality, just as Heartland does on the Heartland website. ISO certification is not one of Keystone's website claims. I'm sure if they had the ISO certification you think they do, they would add that to the list. And the Bing search you mentioned doesn't turn up any ISO certified RV manufacturers, at least on the first 5 pages of results. Coachman and Forest River show up, but when you click through, there's no mention of ISO, nor does a search of their websites produce a result.
A very small minority of consumers subscribe to Consumer Reports so they can evaluate quality and reliability alongside feature, function and price. A very small minority - maybe 2 or 3% of consumers. And Consumer Reports doesn't rely on certifications like ISO. They test independently and collect data independently. I guess they don't see ISO certification as the be all, end all that you suggest.
A very small minority of RV buyers might respond to an ISO certification. The majority respond to feature, function, appearance, and price. The few who try to check out quality ask questions and search the internet, and maybe tour the factories. Would a ISO 9001 Certification tilt their decision? Maybe. Maybe not.
Meanwhile, Heartland continues to focus on improving quality, including building a very expensive PDI facility in Elkhart to inspect every new trailer prior to shipment. Quality will either improve, or it won't. I have more faith in the approach Heartland has taken than I would if they just went after a certification. They're putting a lot of money into their approach - a lot more than it would cost to get ISO certified.
