I've not seen one for a RV before. But, I have seen one in a corporate aircraft. The CEO loved to cook on long overseas flights so they had the burner put on a gimbal that was always level, no matter the aircraft attitude. Unfortunately it cost like a $100K. Great for those with money but not very practical for us poor RV'ers. I do know what you are talking about trying to cook eggs that run towards the low side. Quite frustrating.
