I know this thread has gone on a while.. but we all know that the problems are not just Thor, or Forrest River..... or Brand Whatever.
The real problem is that the RV industry has a quality problem, like no other industry I've worked in. And I speak from 45 years of buying heavy and light equipment. My first job was in the heavy construction industry. Building stadiums. Then I went to college and learned about statistical quality control and finance. Then on to the US Navy, working on as a civilian employee buying ships and outfitting them. (where I REALLY learned about statistical quality control theory and practice). After that it was IT and other systems acquisition for other US agencies. In my "private life" I bought and sold boats, motor and sail, motorcycles, ATVs, sports cars, and even worked on a ski lift. But never had anything to do with RVs.
Then as a retired person I bought a simple travel trailer. From Grand Design. A simple thing. 22 feet long with a simple AC/DC electrical system. Simple plumbing, propane heating and a stove. No slides. No engine. Easy to build. You'd think it was put on a simple assembly line and tested. But what a mess. We had electrical and plumbing problems from the first week. And a short circuit that nearly caught the thing on fire.
I did some research and had an independent PDI, which caught some issues in the shop -- which were fixed. But the worst problems didn't surface until a month or two down the road. Hidden things. Like the under belly heater duct not heating the underbelly. Like the wiring to the trailer jack up front, the short that caught the wiring on fire while underway.
More research and I realized that this is the first time I've encountered an industry with NO companies that are ISO-9000 or 9001 certified. And neither are their suppliers. Don't believe me, check it out for yourself, enter any car company in this database, then try Lippert, Thor, or any brand or company name of an any RV company you can think of... https://www.iafcertsearch.org/
Yes they are following RVIA standards, but guess what, RVIA doesn't follow ISO-9000.
This is nothing new. But what is new is that the industry has consolidated into a few big corporations. Competition is down. Demand is up. And it seems like customers don't care.
As for mine? For the second year in a row my trailer has to go back to the dealer for plumbing leaks, and to have the dealer correct his own installation mistake -- the wiring he installed for the holding tank heaters disintegrated within 3 months because he didn't use corrosion resistant marinized ground connectors -- located where road spray hits the frame. And then there is this: I call the dealer on April 15, and he's so backed up with work he can't even see it until May 14!
I've dealt with I can't count many watercraft over the past 45 years. None of them had as many first year problems as my simple travel trailer. And nobody ever made me wait a month just to look at a car, boat or motorcycle. I'm never buying another RV product. After we visit the major National Parks its going up for sale.
Rant over and out.
