One thing I believe is really important and that is how well will the mfr stand behind his product. This is very difficult to get to. I am a full time RV'er and after listening to a few folks, I would be my position that a privately held RV mfr will give better service than a publically held company. However, that will reduce your options drastically. But one thing for sure, don't buy an RV simply because it has a great interior. Quality of construction is the number one thing and how well the mfr will stand behind his product. Good luck. For whatever it is worth, look at a used Alpenlite. New ones are pricey. I have lived in two of them pulled over 50,000 trouble free miles. These are great units.
