Newbie ~ electrical problem
Hello ~ We brought home a 2008 R-vision Trailcruiser from the dealer (everything was working when we left the dealer lot). About 10 days went by, I checked the charge panel on the range hood and it ...

It could be a bad battery. Being a used unit, the dealer may not have tested, or replaced the battery. It's possible, that battery could be the original, from 2008.
If the battery has a shorted cell, it can act like a very large resistor, drawing more power (trying to charge) than what the converter can put out. While that is happening, other 12 volt systems (lights, radio, detectors, etc) may not have enough power to operate, even while connected to shore power. Shorted battery will not take or hold a charge.
RoyB said "Sounds like the initial reason for the blown fuse is the on-board converter/charger had to put out maximum DC Current for the trailer battery to begin its re-charge. May have been too much current being demanded when this happened." That could happen with a shorted battery.
Note which wires go to which battery posts. Take a picture if necessary. Then, pull the battery, have it charged and load tested, away from the trailer.
While the battery is out for testing, plug in shore power and check lights, radio, detector, etc.
Disonnect shore power while re-installing battery, and make sure battery gets connected propperly.
For future use, while trailer is being stored without shore power, disconnect the battery, or, install a cut off switch.
