Most RV generators are tied to coach battery which has to have a decent charge to turn over the generator. Even with good battery many encounter starting issues often associated with poor grounding and or corroded battery connectors. Probably a good idea to take the time and check the grounds for everything - chassis battery, coach battery, and the generator itself - given the age of the rig they probably need some attention. Also - most built in generators are setup so the fuel line can't draw any gas if the rigs gas tank is less than 1/3 or 1/4 tank - something to keep in mind.
Suggest you write down the spec number of your generator and obtain an operators manual - smokstak.com has a Onan generator forum which is an excellent source for problem solving Onan's. Flightsystem.com is also another site which has problem solving tips for Onan generators - worth a look.
