If your CPAP machine has a unit-specific 12V cord available (CPAP.com is a great source of info on this), and if your TC has a 12V socket near the bed, you'll be fine. This is assuming that the batteries charge while you drive. The factory webpage for your TC says it has 12V outlets, but does not say where they are.
Another option, which I used early in my CPAP days, is a small plug-in inverter and then run the CPAP from that. My little inverter is a Duracell 150W.
If you do not have your CPAP yet, ask your provider for one that will run on 12V.
