Very though list.
You do not need to run the pump when you are blowing air through the system. (#8d) This is the one time you will want to have someone helping you, as they will hold the air to the system, and you can blow out the faucets with each valve.
If you do not have a water tank, you probably don't have a water pump either....as you would be using the city connection for your water pressure. If that is the case, you can get an old garden hose and cut it long enough to where you can pour your "pink stuff" into the hose to fill the water lines. (having someone at the valves to make sure that it flows from each hot & cold fitting into the sink/shower) Having some flow down into the sink/shower drains is a good way to protect the traps too.
Also, if you want to spend the money, you can get a small pump from Harbor Freight and pump the antifreeze into the system, but gravity will work fine, if you've got a ladder handy.
Also, I like to pour about a gallon of the pink stuff into my toilet, and be sure to leave a few inches of it above the seal, to keep the seal from drying out. The extra down in the holding tank (which I will assume is dry) will help keep the drain valve seals moist, and avoid any freezing problems at the valves which are the low point of the tanks.
Again, not sure about Park models, and if you even have tanks, or are directly connected to sewer line??
Blowing out the water lines before adding antifreeze is a good method....some people will only blow out the lines, but some water will still gravitate to the low sections and can freeze. It may not bust any lines, but....it might. Antifreeze will prevent that from happening.
The antifreeze is supposed to be use in 100% concentration, do not add water....or add to water (if possible...hence the reason for blowing out the lines)
Good luck. Once you are finished, you will feel that it was a lot easier than you first thought....and you will find that you can cross off a lot of those steps on your list, but for the first time, better you walk through it....just in case.
