Onan gen stalls on rough roads?

Thanks, guys. I'm going to look up an Onan tech and see what they have to say. Seems to me that a genset for mobile applications should handle running over railroad crossings without stalling. None of my carbureted vehicles ever behaved this way; it's not hard to build a carb to handle jostling.

I was hoping to hear from others either confirming the same experience or reporting that their genset runs reliably under such conditions.
