Just a tip...as you're aware, the 'number' in the model designator generally reflects the 'box' length of the unit...'bh' is usually short for 'bunk house'...that may make your looking more efficient
Re. the jackknife sofa..this current unit has it, and it ends up just being a place to pile boxes of towels or swimsuits or whatnot...our last trailer (2011 Palomino Puma 25BH) had, in lieu of the couch, a small closet in the 'hallway'...could store hanging stuff from the rod, and other things at the bottom...that made a lot more sense...storage, v. a sitting/sleeping location that we rarely use for the designed purpose
for what it's worth
