I've seen some YouTube videos of TT's with Murphy beds. The concept looks very interesting. But the thought of having to pick-up everything so make the space usable for a second purpose would probably drive me nuts after awhile. Kind of like converting the dinnette to a bed and back again every day. BUT.... I've always been a believer is multi-tasking camping equipment ... you know, a hatchet is used for chopping fire wood, but the other end makes a good hammer. So why drag along a hammer if you have a hatchet? Well, this is definitely multi-tasking the same space. It could just work!
