Steve,
I'm just finishing up. Look in the Pompeii Oven Construction forum for George's Pompeii (or something like that) to see my pics.

If I was building a portable, I think I would purchase a Forno Bravo prefab and iron stand, both available in the FB store. Use all ceramic insulation, both under and around the dome, and do a stucco finish, which should be fine for your drier climate east of the Cascades. I think you'd cut down your weight significantly, and the cost would not be that much higher than building an oven from brick.

You might be able to find someone locally to do the iron work for the stand and save a few dollars there too. Otherwise, I agree with the others in thinking that a brick built oven might be too much weight for anything other than a heavy duty trailer.
