I would do alot of research on here and other places about columbus and the 385bh. The 385bh had a lot of bugs, and I've heard of at least 1 dealer that doesn't like to sell them.
There are quite a few other great larger 5th wheel Forest River bunk houses out there. There are quite a few with good success with thiers, like the Sabres, Sanspipers, Sierra and im sure there are others.
Look around on here and you will find tons of info!
