381 Generator

[Rexlowther]

I just bought a 21 momentum 381. Generators are non existent at this point, but I am trying to figure out what size they originally came with. I can’t find it anywhere. Just wanted to know what size I need to run everything!

I think all Mos from the 350 and up are packaged with the Onan 5500. But not all gensets are the same. I know our genset is two 30amp legs but I have seen single leg 5500 Onans in the wild, too, usually aftermarket, though.

Thank you! Kind of what I was figuring but wanted to make sure!
