But even then should we be able to disconnect the battery and have the generator powering everything int he trailer?
Starting your vehicle draws a few hundred amps at one time not a hundred or under.
Truck connection charging: some RV units have a fuse in line with (or in line breaker) the feed wire to prevent reversing the feed wires and shorting the system.
Not charging: if it is not charging plugged in to 110 and if you disconnect the battery and your overhead lights do not come on, you might be looking at a bad converter.
With the unit unplugged in and your battery around 11.5 volts plug in the RV and measure the voltage at the battery. You should have over 12 and about 14 volts.
Question.... the battery will, when charged, power the lights for a while... not just about 10 minutes (bad battery) and no big sparks when you connect the battery (heavy draw)...
... so the 110 system works up to the point of the converter...
If the above fails (battery voltage) you are going to have to check the 110 going to the converter to make sure there is power to it... if you have power in and no power out you found it. If it died it could have taken out the fuse/circuit breaker to the trailer plug.
