On the 3121, had same issue. Ladder was positioned where it could be used with the DS slide in, couch in "couch" position. Couldn't make the couch into a bed and use the ladder. I moved one of the hangers / brackets over. Now, slide out, couch made into bed, ladder right in middle.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
