If you get the Onan 5500 and plan to use it extensively (like running two AC's for long periods), I suggest that you take a close look at how much propane it will go through. It is not necessarily the cost of the propane, but the fact that you will need to fill the bottles quite often.
I opted for twin Honda eu2000i generators, but each person needs to look at a bunch of different factors to determine which is the best solution for them.
