Sounds like a good plan. You will need an external connection point to plug yer generator into the house.
I'd avoid the suicide cord tho, unless yer really carefull.
And that method is only practical if ya have a 220 volt dryer. Otherwise only half of the electric panel will be fed.
Since most generators are tuned to provide 125 volts of quasi electricity ya have ta be carefull of usage and application. Most electronic devices aint too keen on that waveform unless they use an AC adapter. A microwave oven will groan unless most of the big stuff is off.
A 5K watt generator will provide a max of 40 amps of power. So check the rating tags on yer appliances and add up the essentials. My suggestion is not to exceed 75% of capacity.
Never run the generator in an attached garage and never in the rain unless it's covered with an old card table or such.
Hope this helps!
