To clarify our situation: The generator is stored in the corner of the garage and we wheel it out, as far a we can, when we need to use it, leaving the garage door open. When I get that longer cord, it's going to be operating outside!
I didn’t read all the answers above but WHY in the world would you need 27Kw???? We had a 15 Kw and traded for an 11Kw as I changed a few things to lower needs. Even runs the AC if needed and electric hot water. We cook with gas.
We have a Generic and love it. Worked fine for 11 days after an ice storm here knocked out everyones’ power.
Little gennys like a 5KW gas are not made to run for days. They are made to run a weekend or two at the lake or cabin.
