I got boating bags.  The ones for rafting and other really wet situations.  Two problems however.  If they are loaded at a low elevation, and you drive to a high elevation, the air inside (you can't get it all out, no matter what) will expand and the bags will swell up.  If you stow your stuff into them in a warm, humid situation, and go to a cooler one, moisture will condense inside.  Better than being in the rain, but damp, anyway.  I suspect the same would true of any truly sealed container.  The GoWesty bag is not actually water proof, but even they warn you about the condensation.

Are there any others that people recommend?
