I think the 120 volt 2 amp thing is with the humidifier heater running. My Respironics Bipap machine runs off 12vdc and draws less than 2amps DC without the humidifier heat on.

I run my machine off it's own group 24 battery which works fine without recharging for 3 nights. When we go on longer trips I have to charge the battery every couple days, which is no problem as I also have to put at least a couple hours of charge on the main TT batteries every couple days anyway.
As for living on batteries, you just have to figure out what you can and can't have. It's amazing how much power it takes to run a lot of the modern devices we now have available to us. That said, I found we can live fine in our TT for several days on a couple group 24 batteries without feeling we're giving anything up.
