Ok, well I'm probably inviting the wrath of the "build it to the plans" people, but has anyone thought of what it would take to make the Cozy a pressurized plane? I live near the Rocky mountains and one of the nice things that I would be able to do with a Cozy is fly out to Vancouver Island and enjoy SCUBA diving (one of my other hobbies) over a long weekend.
I suspect it would involve many changes (canopy, firewall, access hatches) so I doubt it would be easy/cheap to do, but I'd like to have and idea of what it would take.
I realize that there are oxygen systems out there and that is probably what I'll end up doing, but while I'm at the planning stage I'd like to look at all possibilities.
