I want to control a 12VDC motor from two separate places in my motorhome using toggle switches. This motor drives an air compressor which I want turn on or off, either from outside the coach or from inside. How can I do this?

Use two two-way switches (single pole double throw, SPDT) as below except using your 12V instead of the mains. Then whatever the state of the motor either switch will change it.

Unless you want it to be a reversing switch - you need to put the motor and battery in series.
