well 6000w in lights... probably another 1000 or more in ac... fans not much...
Look at a 10,000w generator at least and make sure it can take the amps. Get all those lights on seperate timers so they don't all try and fire up at once. Set them to stagger by like 20 minutes.
Remember that running watts and rated peak watts for those things are totally different.
Noise is an issue.
Exhaust is an issue too.
Hondas are quiet, indestructible, and expensive.
Look in the Northern Tool online catalog... you'll find some interesting stuff.
You have to take care of them just like a car engine.
Diesels are even hardier and have a longer life.
And it's a lot less sketch and safe BTW having heating oil delivered for your diesel than lugging lots of gasoline around all the time.
Is there a house on the property or even a cabin that you could legitimately have fuel delivered to 'for heat'?
What about biodiesel since it's becoming more readily available and also has the benefit of not being an explosion hazard.
I'v thought about this... also wind power... seems like a major pain in the ass if it's not mean to be a permanent setup.
