I don’t think the Onan’s are any better than others, but generally not very quiet. I’d probably go Harbor Freight 3000 if you want a cheap generator for less (around 700 or less on sale) if you want to go big. I’m sure it won’t be as good as a Honda 3000, but still more power than a Honda 2200 although a lot heavier.
The only issue with running a generator that I’ve heard is startup. Otherwise, most can run on ecomode so a easy start kit is money well spent. Fwiw, even large TCs with lots of appliances only include the Onan 2500 LP version, so I’d think 2500 should be plenty.
