I think ScottG hit the nail right on the head. It's really a mater of ones's expectations that determines "value" and "good workmanship."
Every RV is going to have initial touch up fixes. If not, you'll be doing self modifications and changes within the first month anyway. Its all about your own preception and just how "critical" is it to find a loose screw on a cabine door to you, or someone else. You may fall apart over a loose screw and call the entire camper a hunk of junk because of it. Someone else would just tighten the screw and forget it!
There is no "perfect" RV out there anywhere. All of them DEMAND constant vigilant care and upkeep and this is where the big "myth" about "quality" originates from. Those folks who abuse their campers and then scream they are not good quality are the same ones who never check the oil in their cars, burn out their engines and then scream it was a manufacturer's defect! Same is true with a camper (of any kind). Use it, abuse it, neglect it, and none of them will last more than 6 months. Meticulously maintain every inch of the RV and it can last a lifetime!
You buy an RV, and you have not just purchased a convenient way to take a 2 week summer vacation, you have just purchased a LIFE STYLE. Your RV will require your full attention. It is not a plug-in-and-play-get-it-and-forget-it toy. It's a life long, constant, vigilant, hobby that cannot be neglected (If you want to keep your camper in good working order and looking good).
