Costco has a sale on 9kw Firman generators right now. Don't remember the
price, offhand. It has 110/220. I bought one a couple of years ago. It is
Dual Fuel Propane/ Gasoline. Electric start. Has tires and folding handle.
Good unit.

The Freight, Harbor uses the same engine, likely the same alternator, and it's a bit cheaper. I put one in the 23', worked fine. Note that these are two - pole alternators (3600 RPM) so they will be a bit noisier than an Onan.
