The converters function is to take 120 volt AC electricity and convert it to 12 volt DC to power all your RV items that take 12 volt DC. If your converter is not working (which is also your battery charger), then the 12 volt things run off of the RV battery. However since the converter may not be working (thus no way to recharge your battery), then once the RV battery depletes, all the 12 volt stuff ceases to operate off of the battery.
If the microwave, television and other 120 volt things are also not working, that leads me to believe you have a bad incoming 120 volt problem somewhere.
Plugging into your truck, with a depleted RV battery may take a little bit of recharging before the 12 volt DC things like the jacks or such will work. Do you perhaps have a 120 volt AC battery charger with you by chance?
The links I provided above will give you a brief basic understanding of this and the converter function.
Also have you recently replaced or disconnected/connected the RV's battery? I ask that for another reason.
