This is a set of HAPPIJAC parts that allows you lift and lower your bed in a toy hauler trailer or even in a mobile tiny house trailer or ? When you are not using your bed, you can raise it out of the way thereby making more usable floor space for your ATV, MOTORCYCLE, SIDE BY SIDE or living space & storage. This HAPPIJAC is extra tall so that you can have (2) BUNK BEDS or just one bed. This set of parts has never been used (except for one extra drive motor) . There are a few duplicate parts (drive shaft, bed rail angles, bed rail brackets, up/down control switch, wiring, drive motor, screws & lift blocks) There are a few minor small parts that may be needed to use the extra bunk feature that can be procured from Ebay or Ace Hardware. You will have to supply your own frame mounting bolts or lag screws to attach the frame to your walls. Also included is original factory installation ,assembly & operation papers with photos . This set of parts were in storage for some time and are not factory perfect but could use some very minor cleaning. This HAPPIJAC retails for over $3000 but I am selling it for only $1600 or best offer! I believe it is sized for a Queen frame & rails & mattress, not included.
