Tow behind? Fifth wheel? Travel trailer or toy hauler? Whatever you buy, you're going to find issues. The RV industry is forced to build products using lighter weight materials. The materials alone lend themselves to issues. They are never as strong or resilient as what you find in your home. RVs are subject to road vibration that your home is never subjected to, and this causes problems over time. The unit you choose will meet your criteria for design, space, and usability.
There is no perfect solution. Only solutions you can comfortably live with. There is no manufacturer that is "better" than any other. All have quality control issues, and all produce products that are good on some days, great on others, and from time to time are really crappy.
Whatever RV you buy will be made by humans. Remember that when you discover problems. Which is why you purchase extended coverage well beyond the one year manufacturer coverage.
Make your decision based on what YOU like. Don't base your choice on what some hot head writes in a forum. That's why I won't recommend any unit over another. I know what works for me and my family. You have to figure out what works for you and yours.
I own a Voltage product made by Dutchmen. Friends own Jayco products. Others have Keystone rigs. Everyone likes what they have and simply works around any issues that develop. We are not lemmings. We choose what is best for us, and live with our choices.
Again. ALL rigs sold today are good and of sufficient quality to get the job done. Make your decision based on what FITS YOU.
Hope this helps. If you want to see my setup to to http://myvoltagerv.com
and learn more. I love my fifth wheel, not because it is the best trailer in the world, but because it's the best trailer in the world for me. See the difference?
