Two links, posted elsewhere recently.
One is "get it made in a day or ten" with or without benefit of a workshop, the other is, well, Victorian.
(Somebody was also making Basque type shepherd wagons/chuckwagons a couple of years ago, might still be doing that--and then there are those gorgeous if made strictly by the plans teardrop trailers)

This one opens on a Java slide show--one of several on the site:

The site I remember for sheep wagons wasn't this one, it was, I think a lot more "sheep wagons as working wagons."

Amanda, I really like the Victorian model - quite ornate! Today, I saw this pic of a gypsy caravan owned by an elderly man over by the Salton Sea (in the far southeast of California) - pretty colorful, too...

The above came up on a Google image search of "Gypsy caravan" and while not exactly road ready it is interesting - MORE INFO (http://www.travelblog.org/Photos/49957.html)
Friend of mine's Gypsy granddad lived with his wife in a trailer park in Arizona somewhere. What would how be considered a biggish travel trailer, I gather. He was kind of a legend in the family, supposed to be the only one who maintained contacts with the Romany community, where the others had become "real Americans." So Fred, at the end of a trip around the country (think of Kerouak with the Mexican woman in On the Road type environment), comes to visit. The old man passes him a couple of buckets of water so he can wash up before coming in, takes him to the barber shop. No better than the family Fred had gotten away from. But even though Granddad and his wife had been there for 20 years, had a porch with vines on it at the front door, every night the old man backed his car up to the trailer and made it ready to hitched up. Just so if he really wanted to he could leave in the morning (if the tires were still good, if they had remembered to renew the license during the last 5 years, if, if, if).
That little trailer-like house looks like it could have had the same story attached to it.
story--and picture--sound like that's a working fireplace for the place. But the fireplace sure looks like it once belonged to a house on this side, not where the little place is now.
