Solar system with both 12v and AC inverter
So we should be picking up our new Fuel Toyhauler on Saturday and we need to install a solar panel kit with inverter. I have about a zillion questions regarding solar, but my most pressing question...

There's no problem at all with having the same battery bank supplying both 12V loads and an inverter. That's the most common setup for RVs with an inverter, and in my opinion the most sensible, as it allows you to use all the available battery power in whatever way is necessary without artificial divisions.
Your CPAP machine would probably be just fine with a pure sine wave inverter; indeed, it would have no way of "telling" that the power is from an inverter and not a generator or the utility. A modified sine wave inverter is a different story altogether. That said, the DC to DC converter will probably be more efficient overall (you'll waste less power than using an inverter and the usual AC power supply).
