We are very interested in the Oliver trailers too but would also like to have bunk beds for 2 kids. Wow, it has been 10 years since the original post. I take it there is no update to the bunk bed option or mod.
To share and hopefully build on this idea ...
After researching, I think a promising option would be to somehow use the Kid-O-Bunk and maybe build a platform for it over the dinette. Another option would be to set it up on one side of the master bed.
