A good friend of mine has had two class C's with Onan generators over the past 15 years.
The current one is brand new, and you have to crank it for over a minute to get it to fire at all, then you have to restart it 2-3 times to get it to stay running. Dealer can't find anything wrong, gave up and says it's normal. Previous one was about 50/50 whether it would run at all.
Maybe you should explain to your good friend that these need fuel to start!
If the RV's propane system has sat unused for awhile it helps lot if the propane line is purged for example by letting "gas" flow out of the stove burner until it is combustible.
Just pushing the starter button, complaining and blaming Onan is another way of purging the line
:h
The gasoline versions have a prime function built in to the start switch. You hold the stop/shutdown switch to prime the fuel line and fill the float bowl prior to starting the generator. Some of the RV manufacturers failed to follow Onan's recommended fuel line length and rise limits - This results in the OEM fuel pump mounted on the generator having to pull fuel too far (it does better at pushing fuel). The solution is to add a second pump close to the fuel tank and possibly eliminate the OEM pump.
