You don't mention which Outlook model you own: 29B, 31C or 31H. Also, is it on a Chevrolet or Ford chassis?
According to the wiring diagram set for a 29B (link here
) as an example, the following must be true for 12V from the alternator to reach the house loads, assuming all wiring is correct and intact
1) Engine must be running
2) Alternator must be working correctly
3) BATTERY MODE SOLENOID must be working correctly
4) AUX BATT switch near entrance door must be on
5) COACH BREAKER PANEL (40A) circuit breaker in chassis electrical box must not be tripped

"twinboat" is correct. You can connect a small inverter to your existing 12V system, staying within the current limits for the fuse feeding the circuit and the 40A breaker feeding all the house loads. If you wish to install a larger inverter, you wire directly to the battery, with its own fuse.
Converter/chargers (such as the one in your coach) and inverters can get along. Converter/chargers and inverter/chargers often do not get along. Should you want to install an inverter/charger, read up
on what changes to the converter/charger installation you will need to make.
