There are lots of good reviews around here for winterizing but you have to consider the climate of the poster.
My suggestion and I do skip parts because there are some really good reviews here.
My main point is getting the adapter to pump the antifreeze and sources.
Find your water pump. Easy way to do this is to run it and listen for the noise. Usually you have to remove a panel to see it.
OK, what fitting do you have on the supply side of the pump? It's the hose that comes from the fresh water tank.
Look at the brand of pump. I have a FlowJet and I bought this adapter. I went to Home Deport and bought 3 feet of clear hose that fits the adapter.
Buy 3 gallons of the pink stuff. In my area Walmart is the cheapest.
Open all faucets and drain everything including the water heater tank.
Set the bypass on the water heater to bypass. Close all the faucets and drains.
Install adapter, stick the hose in a gallon of pink stuff and yada, yada.

I do the same as you, but IMO, if there is any water in the plumbing lines, that water will dilute the antifreeze, raising its "freeze point". On the "good to 50 below" antifreeze I use, a 50/50 dilution is only good to 10F. That's 60 degrees "less protection".... How much water is in the plumbing? How long should you let it run to push that water out of the lines? Are you sure all/most of the water is gone or if diluted, how much ????
All those questions, at least for me, are "answered by removing as much water as possible before filling the lines with antifreeze".....
So, in the "not so frigid temperatures of -30F," I do as much "positive protection" as I can, by keeping the antifreeze as undiluted as I can.
In south Louisiana, I sometimes used compressed air, most times just opened the low point drains but a gallon of antifreeze would last me 2 or 3 years... Up here, not so much.... YMMV
