Sorry for going off line for so long my wife and I just had a baby boy.  So my wife has had me running in circles.  Anyway thanks for the responses.  They are were insightful.  I think that you all have changed my mind to get a diesel.  I have a diesel truck so rotating fuel wont be a problem I will just have to keep filling the cans up after someone steal it because the price of fuel is too high LOL ( no I guess that is not funny).  I think that I will look in to wood fuel or biodiesel for both my truck and generator.... I still think I "need" a larger wattage generator so I will at some of the sites you have suggested.  one other question I would assume that the rotation problem is getting the sin waves to match up and I think that the parallel panel will fix that but the question is if I have 2 5000 watt diesels is does that make 10000 watts or do I loose some energy in the switching?
