As a bonus, the air is really dry (the dewpoint is -70F).

I had a steel dive tank. It weighed as much, if not more, than my pancake compressor. Getting it filled could be a problem. Some dive shops won't do it unless you have a dive certificate. You can get a carbon fiber wound tank that firemen use for breathing. They are a lot lighter and can be filled to 4500 psi, but there again, filling could be a problem. I use these for air rifles, but getting them filled was such a frustration, I bought a high pressure compressor.
Use the pancake compressor, it's the easiest solution. Take some other junk out of the coach to compensate for the weight.
