that's right, as batteries are not a 'specific' output device like others, as far a time goes.
Your inverter will output 120v power, for sure, at least as long as you have enough battery power.
Your shore power will give you 120v power, normally, as long as it has power itself.
Your generator, the same, as long as it has fuel.

While batteries give 12v output, the 'time' it will last is not indefinite, therefore the 'amount' of that 12v you use is going to impact the 'time' you have to use it - and it will be different in almost any and all situations.
Even if your neighbor has your exact same coach, parked right next to you, and under the exact same conditions, will probably not have the same outcome. It's just the nature of batteries.

This reminds me of the time I helped with my city's power bills - the billing department seemed to be the front for many calls and complaints about why the bill was so 'high'.
Inevitably, the conversation went from why 'my' bill is so high, to why is my bill not the same as my 'neighbors'??
The reality is that the neighbor's house may be better insulated.
They may run the air conditioner less.
They may not leave the front door open.
etc.,....

It's the same power source, and will bill for the same amount of usage, but one house that 'looks' like another house may not necessarily have the same bill!
