Generator to run three RV's?
My family is considering buying some property to use as a place to bring our RV's and do some ATV riding on local trails. The properties we are finding do not have power. Some have power at the road a...

50 amp service equals 12,000 watts (2 legs of 50 amp = 100 amps @ 120V) x 2 vehicles equals 24,000 watts. Add in the 30 amp coach at 3600 watts and you need 27,600 watts to properly service all 3 RV's. You would need a substantial generator to supply the power to all 3 and that would be done by feeding the service from this 30,000+ watt generator to a sub-panel from which you could run 3 proper circuits to 3 independent plugs that the RV's could plug into.
If you want to run all 3 rigs at max output, you need a giant generator.
Assuming you are willing to be more modest, you can cut that back quite a bit.
An aircon unit will typically pull around 1500w continuous, so 5 units would be about 7500w. You need some additional overhead for other misc. loads and to cover startup loads, so maybe call it 10-12kw...no where close to 30kw.
Of course, if this is northern Michigan, you can probably get away with the 50amp rigs using a single air/con unit (living area during the day/bedroom at night), this would cut your demand back to 4500w rounded up to maybe 6-7kw.
We know some folks who do 3 30amp rigs on a 7kw generator. Seems to work fine.
PS: I would check on pulling power from the grid if you can get it but even up north don't be surprised if they don't want to provide it without you pulling a residential or business permit to build something.
