Onan Backfire - Not A Good Thing
When not traveling I run my Onan 2800 for one hour under a 1500w load every other week. Always, when starting it takes a couple of tries for a few seconds for it to start, drawing up gas from the fuel...

I have the same Onan you have and I used to always put Stabil into the gas tank and run the generator for awhile before shutting it down. Upon trying to start it after it had been stored for a couple months, give or take a few weeks, it would always backfire VERY loudly and didn't seem like a good thing to have happen.
I have since quit adding Stabil to my gas and instead simply drain the carburetor bowl of the Onan via the drain screw and haven't experienced any more backfiring. I also do not exercise the generator while the rv is stored for long periods of time like 6-8 months or more because my rv is stored inside my garage and the weather in Sacramento is relatively mild. Been doing this for about 7 years or more without any problem.
To make things clear, I still add Stabil to my gas tank, I just don't run it through the Onan.
