Removing sofas from HappiJac PNP Bed Lift Bed/sofa combo

This is probably close enough to it and the manuals are available on this site: http://www.mirageinc.com/happijac-power-bed-lift-w-optional-double-bunk

I think the manufacturers take that unit and put in the sofa on the lower carriage option. I don't see why it couldn't be removed. You can remove the stops in the track to get the upper bunk to come down further. Those stops are most likely there to prevent a liability issue with a crush risk.
