I have the layout pretty much done, besides one hinged table that would fold off of the wall. I'll add that later if I need it.
The tool chest is on castors so that comes out for easy access, and the top then is a table/work bench. The bed is just an inflatable full size (double) bed, $22 from target. The TV was free (already had it). The DVD/CD/stereo was $50 on craigslist. I had to buy about $20 in lumber so far... Also fixed the side door that wouldn't open since the side was dragged...
The extra room under the bed is for the welder and small air compressor, which will both be easy strapped to the floor for transporting. The bed is high enough that I can also sit under the bed on my camping chair.
NOW it's time for paint, then hooking up the surround sound and 12V lighting!!!
