Fuel tank winterizing

[sidelock]

I have a Moeller 40 gallon plastic fuel cell in my 18 SF and I'm debating whether to leave it empty over the winter or fill it with fuel and stabilizer. I'm located north of Buffalo NY and since our temperature varies dramatically from summer to winter, condensation is obviously a concern.
I emptied the tank a couple of days ago in preparation for winterizing and I'm undecided what to do.
Any advice or opinion that may help in deciding what to do would be appreciated.
