I had a Keystone Passport and had no problems. I now have a KZ Spree and love it also. KZ is a good name brand. There is always a chance to get a lemon with any brand. I did a lot of research before I bought mine and felt pretty good about the purchase. I have no complaints and we love it. Finding a floor plan you like and a weight you can tow are probably the most important things that will make you happy with what you end up with. There are no makes that are head and shoulders above the others. I have a KZ, love it and would recommend it. I also had a keystone and would recommend one. This is based on my experience, others may disagree.
