UPDATE: it's been about a year and a half since Timothy posted this here.....and a few other folks have built this vardo, one in Canada, one in Mississippi, Tims son, NC I think, and now MINE built in Alabama...
I'm just about to pull my vardo out of the Garage, (built it off trailer and will mount it later due to height restrictions in the Garage)...still doing finishing trim work, the slide out table needs mounting under the bed, and the door needs the window installed and i've yet to hang it on hinges...
All credit to Timothy, please take a look at the book, buy the templates, and then build one....(I owe Tim that one because I did none of that.....I took basic info from his site, used the photos to exstrapolate a little, added touches gleaned from two or three other sites, and took to cuttin' and sawrin'....the results will soon be forthcoming, the Polyurethane is drying on the tabletop as I type this, but until I get the photos so far posted (I took not nearly as many as you will find on the link I'll post shortly) take a look at the BLOG for this one built in Mississippi.....
