On just about any rv your battery will run out long before your propane. I wouldn't worry about using the stove too. If you start with a full tank, it will last you more than a week unless you really go crazy. Not real familiar with MH's, but on parent's MH, the tank had a gauge, so at least you could monitor your usage.
But to dry camp more than 7 days - I would have a plan for the battery and the holding tanks. At least for us, those are issues long before propane.
Enjoy the trip - I'm sure the grandsons will have a great time!
We can dump the tanks no problem, two dumping station in park one close to where we will be.
