We LOVE it. We are currently a family of 3 (and a Golden Retriever) with a baby on the way. We've spent (literally) a month straight in it. Right now we have all the room we need. Our Son uses the upper bunk to sleep and the lower has become our "storage" area. Once the new one arrives we need to rethink things but we are not using any of the under seat or bed storage at all right now.
We had a few initial issues within the first few months:
1)Leaking toilet
2) bathroom door miss aligned
3)cracked black tank
All were handled under warranty with no problems and from what I understand ALL new RV's have a "break in" period.
Again, I'd say go for it. We spend a ton of time in our's and my wife runs a blog about our travels, etc. Here is the one with our camper:

Good luck and I'd be happy to answer any questions you have (if I can).
