Thanks max+sophia!
The Murphy is a XL Twin because I'm 6'3". I can't sleep crosswise so this is my solution. I can't find any free plans for the Murphy Bed/desk combo which I deemed necessary for the space lost by having a bed lengthwise. The desk will also serve as kitchen counter. Anyway, no plans just means I look at a bunch of pictures and spend time figuring it out. Yesterday I finally succeeded in finding the magic location to place the pivot so the bed can fold straight up and not hit the ceiling and still clear the wheel well. I've cut the parts for the desk/counter and this week if the rain holds off I'll do a temp assemble and begin trying to figure out how to hinge it so it stays parallel to the floor and supports the bed in the down position. There is probably some mathematical formula for these things but darned if I am bright enough to discover it.
I will be stealth camping in this low top while I continue working until I bank a pre determined wad of cash to keep me comfy until I can draw retirement funds. Thus I chose a low top. What I really would like is a 12' cutaway box truck. Nice and square to build, wide enough to sleep across, and more than enough space. I couldn't afford the more than 10K going rate and going into debt didn't make sense. I may learn that I can be comfortable in my current build. If not, well, I'll figure out how to upgrade!
I hope you find an adequate replacement for Greybeard!
