10000 watt / 120 volt = 83 amps. The only way it would is if the wiring has all 3 AC's on one leg of the generator power. In most cases the generators are sized so the RV can operate all required systems.
On my coach I have an Intellitec EMS system. When the generator is running it sends a 12 volt signal to the EMS circuit board at which point the system is disabled and will not shed load.
I do have an EMS. However, when hooked up to 50amp shore power, it does not show my total draw. It only shows it when hooked up to less than 50amp. The owner manual confirms this is correct.
The gen has/does run everything no problem. I have made 8 hour drives with all three AC's and the fridge running off of it. My wife has even heated up coffee in the microwave at the same time. I ran it two hours yesterday just to test everything. No issues while sitting in 102 degree heat. The only time I have had the problem was in the extreme 118 degree heat.
I have the same system so when the generator is running, it doesn't show the load. Again, the owner's manual confirms this is correct. Which honestly seems silly, as that is when I would want to know the most!
