Save your money, "quality" is subjective, what is deemed good by one person will be another persons "lemon". You can drive yourself nuts worrying about perceived quality of a supposed high quality brand.
EVERY RV manufacturer turns out some "lemons" it is bound to happen when you build THOUSANDS of "copies" every year, there is no exceptions to this rule.
Rather than torturing yourself pouring through thousands of pages of "opinions" (aka reviews) find the layout that suits you and buy that one. All with the understanding that there is a chance that something can or will go wrong that may need to be taken care of under warranty.
Absolutely, good advice....
... been camping since '75... tents, popups, TT's, 5th. wheels... shop around and notice things that relate to better workmanship... cabinets, heated tanks, black tank washouts, duct air and heat, insulation packages, window treatments... so many things that can make for a better camping experience. 'Window dressing' makes many look great but look past the "bling"... do a bit of research... my newest will be picked up next week... just bought a Forest River VLight 30fkss with a 'diamond package'... I could have spent more money but all in all I am satisfied with the unit and with a full bumper to bumper 7 year warranty (which I think is a good idea) I think it will fit my bill nicely. My previous camper was a Keystone Montana 5th. wheel that I had for almost 6 years... took it all over the country and only had very limited trouble... took a 3 month cross country with it and it never gave us a minutes trouble and yet, I have talked with folks that say they had a lot of trouble with their Montana... so, who is to say... just pick one that fits your requirements and keep it properly maintained... keep it up to date and watch for signs of trouble... most any will give you good service if you work to keep them ship shape... that is my opinion only and I am sure others will have alternate advice... believe no one, not even me... do your research and have a good camping experience.;)
