Best bunkhouse for young couple and newborn

Hi!

We are looking to get a fifth wheel. It will be just the two of us and our newborn with 2 dogs. What is the best kind of bunkhouse for fulltime families? I love the midbunkhouses but those are hard to fin . I want something with more than just a loveseat in the living room. Also, have they made older model rear living, bunkhouses? I can only find new ones.
Thanks
