We've seen 3 vardos similar to that one on the road, all in the PNW.
One (at a reststop) was built on a 6x9 trailer with a neat slide-out porch. Wish I could find the pic. It was tiny, but well done (not super fancy), painted gayly (no wisecracks), and had a curved fiberglass top her brother had laid up.
Much the same as a van, she had it set up cozy living in moderate climates. She towed with a mid-sized Toyota with a low topper.
This gal was all in tiedye/beads and a good story teller accompanied by her flute. We all took our lunches to a picnic table and had a fun break for about 4 hours. A van pulled in and he joined us with his dog and guitar.
After they boogied off we figured....nice roadside park with a stream and a hiking trail in the pines....heck with it, we're spending the night.
Next morning, a nice breakfast and off on Hwy 26 and Portland.
I've thought about those kind of trailer/tiny houses and the vardo makes the most sense to me as long as doesn't look as vulnerable as the OP. I have the skills to build a really nice one, just not the place or tools anymore.
BTW...that reststop on Hwy 26 is about half way to Portland from Seaside, Or.
Patrick...you know the place??
