Double recliner vs jackknife sofa - the clear winner is...

As an aside, just noticed an odd thing on that Jayco page. The photo at the top shows what appears to be a Lippert frame (top mount coupler) while the photos below the floor plan def. shows a BAL frame.

How can you tell who the builder of the frame is by the location of the coupler? As far as I know, it is the trailer manufacturer who determines where the coupler is located - not the frame builder. I believe all frame manufacturers build all three types - top, middle, and bottom coupler frames.
