Good info everyone.
I have some duct tape on a pencil in my motorcycle kit, but I like the sound of the card technique even better.
The Resmed zipper case has individual compartments for everything, with pictures on each flap, so that acts as a self-documenting checklist. I used it for a 4-day weekend in Orlando a week ago, and it worked out pretty good.
I even took my own distilled water on that trip, putting some from the gallon jug into a rinsed out 2 liter bottle. Where I'm going on this upcoming trip is a major city in Brazil (Recife), so I'll be able to get distilled water, but probably won't be able to get Resmed parts easily.
Ordered an extra medium pillow yesterday, and will bring my large pillow as an extra backup. Also ordered some filters yesterday.
Good idea on the adapter and extension cord. I think as long as I don't drop, lose, or tear anything, I should be ok...
