Predator 3500 - surge capability while in eco mode?

Has anyone seen any videos or performed any tests showing how well the Predator 3500 handles surge loads while in eco mode?

I already own a Yamaha EF2000is but it struggles to start our fridge and/or freezer in eco mode. I'm hoping the Predator 3500 has much better surge capability that I could leave it eco mode for the low noise and fuel savings but reliably start these two units up.

Because of lawsuits, Edison is saying they could turn power off for days when it's dry and windy out. Figure I should get ready.

Thanks
