Bunk bed

[Whiteberry]

Hi all,

We are considering buying a 2010 Topaz as we really love the look and quantity of the trailers,  however sleeping the 4 of us seems to be tricky (2 X adults 1 X 3yr 1 X 12yr)

I have read that some people have a bunk bed above the king.
Would anyone have a picture of what it looks like and how it works?
