Drop down bed in toy hauler

[Jestercyco]

I have a 29 MBV XLR TH with the Murphy bed in the back. I want to replace the bed with a powered drop down bed. I like the kind that have 4 posts with a screw system or with the chain drives. I have seen some names of these type beds and would enjoy some input and /or ideas on this. I build protype equipment for a living and am quite handy at fabricating. Just looking for some of the knowledge of this people at this forum.
Thanks in advance!

I have a Work and Play toy hauler with a HappiJac 4 post double bed. It is the chain driven style. Over 2 years with no problems. HappiJac had a web page at one time, but the word on the street is they would only sell complete beds to dealers. You could buy parts there. There nay be other stuff out there, haven't looked as we are very happy with ours. By the way, it is the only bed in our camper and gets used every night, down at night, up during the day.
