|Power in the wilderness

How do you provide power to a required medical device (not mine, fwiw) in the wilderness?|
Well, this is what I've put together:
1 deep-cycle marine battery
1 400-watt inverter
1 battery box
(charger in case it goes flat)
Put the battery in the box, along with the inverter. Strip off the cigarette lighter plug on the inverter, wire to the battery connectors. Plug CPAP machine into inverter.
I've already confirmed that the CPAP uses 1.5 amps (according to the power requirements on the device), so if we're good about unplugging the inverter (remove a lug -- if this works out well I'll add a cut-off switch) it should last for Baitcon. If not, well, I have the charger, and in an emergency can always use the small generator, though I'd prefer not to have the noisy thing near where people (including myself) are sleeping.
(The guy at Sears, when he heard what the battery was for, was simply amazed and enthralled by the concept of building a power supply like this. Is it really that unusual?)
I should have a small multimeter somewhere, if I can find it before heading out I'll add it to the box so I can check voltage levels.
Now let the chorus of why this won't work and how I'm going to kill everyone with my infernal device begin.
Assuming it does work and doesn't result in a China Syndrome meltdown, I wonder if Make would be interested in a writeup, or if this is too simple a project?
