We just bought a used 24" Class C motorhome that does have an on board generator.
Did you mean "does not" ?
It sounds as though, that is what you meant to say.
You will need a 2000 watt Generator to use the coffee maker & I doubt you will find one that will fit the compartment dimensions you gave.
As far as the CPAP. I've been using one (without humidifier) for close to 20 years & I DO NOT use my Generator or coach batteries to power it. I have a "dedicated" 35 amp AGM deep cycle battery for that purpose only, it is very small, compact & portable. If your CPAP is a newer model, it should accommodate the use of the manufacturers 12 volt power cord & can be connected directly to the battery, as I have.
