I wish I knew what RV quality was. It’s an elusive thing and it changes often. Its factory dependent, shift dependent and time of year dependent. There are materials, appliances, technology, production methods, engineering, supervision, training, schedule, philosophy and environment all to consider. Leaks happen in entry level trailers and high-end coaches. Screws miss the mark, the glue does not hold, the weld was bad and the supervisor was having a bad day. As someone mentioned, the same model made a week apart could have a serious problem and the other could be perfect. A lot depends on the level of engineering, the maturity of the design and the training and supervision of the assemblers. I am about to buy my 5th trailer in 18 years. It will be a two axle travel trailer. It may be new, it may be used. It may have any sort of wall construction and siding configuration. It will be between 26 and 30 feet long and it will have a slide. I have looked at 50+ trailers just in the last 2 months, new and used. There is a LOT of variability in quality and condition. Whatever I buy will be checked and inspected in great detail to determine just what kind of shape the unit is in before I hand over my money. My advice? Decide how much you can spend, find a dealer you can work with and trust, find a floor plan you like, look at multiple brands that have the same or similar plan and see how each company does it differently, write down what you see, what you like and don't like. If you have kids, buy a used trailer. If this is your first RV, buy a used trailer. If you have not towed before, find out from the manufacturer the tow rating of your van, SUV or truck. Don’t trust the RV sales person to know. Go to an RV show and talk to the factory reps that will be there. Ask questions, it’s always a good idea! As you look at rigs, take pictures, talk about it with friends that have some experience (if you don't) and then try and make a deal. Then inspect or pay a 3rd party to do a full inspection, then do a walk through, have the dealer fix the problems now (or negotiate with the seller for a lower price) and then and only then sign the paperwork and hand over your money. Sounds like a lot of work, I know, but it will pay off! Good Luck.
