I have the same generator as the OP, plus an older style Manual Transfer Switch that I put in when Hurricane Sandy hit in 2012. I put a power inlet box outside the house and used 10 feet of 10/3 wire to hook the power inlet box up to the MTS.
I went this route versus an Interlock because of my wife. She is deathly afraid of anything that has to do with the electricity in our home, and when I told her about the Interlock versus the MTS, she said there is no she was going to open up the load center and start flipping breakers and as she says "that other thingy" to get power to the house.
She liked the idea of the MTS because it is simple to use, and runs only the things we need to stay in our house when the power is out. We run our oil burning furnace, the sump pump, our well (for water), our septic system, two refrigerators, two kitchen outlets, the lights and exhaust fan in one of our bathrooms, our office and the outlets that run my fish tank, that also run the TV and fios box.
This gives us the ability to have heat, keep the basement from flooding, take hot showers, flush the toilet, keep our food cold, eat hot food (using a toaster oven or the microwave), watch TV, have computer and internet access, use the bathroom, and charge anything that is battery operated.
But the most important thing of all is that my wife is not afraid of the MTS. She knows how to gas up the generator, wheel it over to the power inlet box, start the generator, hook up the L14-30 cord and then walk into the basement and just flip the 10 switches on the MTS. For some reason, this does not scare her because at no time does she have to open the door on the load center and have "electricity get me".
That, and I know in a power outage, if I was not home, she would not keep track of what breakers she was turning on and off to supply power to different things using an Interlock, as you have to do that in order keep from over stressing the generator.
I would have preferred the Interlock, but because of my wife, we have the MTS and it works great, is easy to use, and most of all my wife is not afraid to use it.
Here is a picture of my power inlet box outside the house and the MTS hooked up next to my load center in my basement.
