Charging batteries
I have a 07 Keystone 5th wheel with 5500 Onan gas generator. When I run the generator it only charges up the batteries to 11.87 volts. Is the invertor the one responsible for charging the batteries...

When hooked up to shore power or generator measure the voltage at the battery - should be 13.2 or higher. If the voltage to the batteries is OK then it's likely your batteries need replacing - have them load tested (it's free). If the voltage is less than 13.2 then test the voltage at the converter - if the converter isn't producing voltage check for the fuses on the converter and if they are OK you likely need new converter.
If voltage at converter is OK but not OK at battery check for blown fuse/breaker between converter and battery.
