Quality means something different to each individual. I would not presume to say who is right or wrong, we all have our own expectations. What I do know is that those who agree with me are right, and everyone else is some level of wrong :)
I'm pretty happy with the quality of our Cougar. It hasn't fallen apart on the road. And it didn't cost a lot. I think you call that, value, but I have to call it quality too, because the unit is doing the job it was designed for. Others will just scoff at that. Thing could have been done better. The foam around plumbing penetrations is sloppy and looks messy. The bubble cover on the aluminum corner molding at one corner was too short, and when it got hot it would slip out of the channel. I did a little cleanup to the edging on the countertops. I wouldn't call that poor quality, but others would.
I don't have solid surface countertops. Poor quality? Not to me. Then there is the lack of a cap on the rear. Oh the shame, such poor quality! Sarcasm here.
My frame is not broken. Running gear, including brakes, is holding up fine. I don't have shocks. Proof that they are not needed. My spring bushings are not worn out, proof that you don't need wet bolt kits.
Nothing leaks. Not the pipes. Not the roof. Not the box.
But to some, this is a low quality brand. Proof, not everyone agrees on what quality means.
About the most annoying thing I'm dealing with now, is the plastic fender skirts flexing and pulling the screws through, caused by driving in winds. I can definitely see where they cut cost and weight on those and it is a real pain to replace those. Should have lasted more than 8 years.
Someone said we defend manufacturers too often. But I've seen some extremely petty complaints too. A lot of times it is just buyers remorse due to unrealistic expectations.
Ideally, quality should be the same in a $30k trailer as in a $130k trailer, and the cost difference would just be features and size. Ideals and reality rarely meet.
This got long. Maybe I shoulda just written a book.
