Winterizing My Rockwood 2904SS

First winter with our new camper...(we call it Rocky)...and this RV has some new features our old 18-footer did not:

-Outside "Antifreeze Inlet". It looks like a standard hose connection but I haven't found a hose for this....I'd love a see-through hose so I can see the antifreeze being sucked in. What do y'all use for this? Why doesn't Camping World have something?

-Water Filter. From what I've read in here, I'm going to install a bypass around it to avoid problems. (And thanks to the engineer who put mine WAY inside the RV...couldn't put it near the door, could you?) I may just remove it altogether...an in-line water filter on the outside hose is not expensive.

If anyone has a checklist with pictures they can share, that would be appreciated!

I use the air blow out plug in the antifreeze suction side with a piece of clear tygon tubing to pull from anti-freeze jug. I removed my water filter and by-pass it (grey pex) and modified it to be used outside of trailer in-line with fresh water hose.

Okay, after reading every post in here about winterization and watching hours and hours of youtube videos, I've created a checklist for winterizing.
(I do not have an ice maker on the fridge nor a washer and dryer and my trailer has the external antifreeze inlet and has the water heater cut-off valves.)

I won't run through this for about a week-and-a-half so maybe some of you experienced folks can see if this sounds right:
Rocky Winterization Checklist
4 bottles of RV antifreeze; small trash can; rags/paper towel; Ziploc bags; tape; blow out plug; antifreeze feeder plug; 1&1/16ths socket with extension & wrench
Ensure all gray & black tanks were thoroughly cleaned & emptied prior.
Wash RV from top to bottom.
Ensure tires are at proper inflation, don’t forget spare tire.
Locate & open the low point drain lines. There will be one for the hot & cold water lines. Using the water pump will help force water out, but turn it off as soon as the system is drained.
By-pass the water heater. (Hot/Cold lines OFF & middle bypass valve OPEN)
Ensure electric switch on water heater is off. Relieve pressure then drain the water heater. Remove the drain plug/anode rod.
Open faucets to relieve pressure, then put small trash can underneath water filter glass holder, unscrew it, dump water, remove filter, & replace.
Insert blow out plug to city inlet water connector, connect to compressor, & set for 30 PSI.
One by one, open all hot & cold faucets to let all water blow out; don’t forget the toilet valve & inside & outside showers.
Turn on water pump & quickly clear all of the lines. (Don’t let pump run empty for long, 30-secs tops.)
Recap all drains & close all faucets. Remove blow out plug, then connect to, & blow out, black tank cleaner.
Disconnect the inlet side of the water pump (the line coming from the fresh water holding tank).
Connect a piece of clear tubing to the inlet side of the antifreeze inlet valve & put the other end into a one gallon container of non-toxic RV antifreeze. (One person outside manning the antifreeze & one person inside.)
Turn the water pump on & pressurize the system. Starting with the bathroom faucet, slowly open the hot & then cold valves until antifreeze appears. Do same on both shower lines then the toilet.
Move to kitchen & open hot & cold until pink antifreeze flows.
Move outside & open hot & cold faucets on outside shower until pink antifreeze flows.
Turn the water pump off & open a faucet to release the pressure.
Pour a cupful of antifreeze down each drain (bathroom/shower/two kitchen sinks). Pour a couple of cups in the toilet & flush into the holding tank. Put an inch or so into toilet.
Make sure all the faucets are closed.
Insert anode rode into water heater, but not snug. (Prevents rust from developing.)
Cut tops off of the empty antifreeze jugs & open both gray tanks & black tank to empty them.
Go from back to front of trailer, in every cabinet & drawer; ensure nothing is in the camper that can freeze. (Food, cans, liquids, batteries,etc.) Also remove all food & anything made of paper. (Mice)
Clean out any liquids from sinks/tub/toilet with paper towel.
Remove TVs & remotes from trailer. (Store remotes in ziplocs & tape to TVs)
Drive camper to RV Storage lot. Bring awning covers & clips & tire covers & bungee cords.
Lower the stabilizers on the trailer.
Chalk tires on both sides
Prop fridge doors open.
Ensure ALL windows are closed & all blinds are down.
Cover tires well with covers.
Install awning covers & holding clamps.
Remove batteries & propane tanks. Hide all cables & safety chains underneath plastic tank hood.
The unit is winterized!
INSPECTIONS DURING WINTER (On a dry day to avoid introducing moisture):
Ensure tires are inflated, don’t forget spare.
Check outside & inside for any signs of critters. (Droppings, shedding’s, etc.)
Inspect awning covers & tire covers & caulks. Tighten & loosen anode plug to prevent rusting.
If tires are looking like they are settling, drive camper a few feet forward or backwards.
Air out camper, check all windows & seals & look for any signs of water or mold.
Check for signs of movement by high winds, adjust if needed.

Great list. I'm new to this game as well so I'm gonna copy and use this list for myself. One thing though, why empty the black and grey tanks after the antifreeze is in there? Aren't you supposed to leave some in the tanks? Creasy tank as well? Like I said I'm new to this so I'm probably wrong.

What ever water remains in the fresh tank is not enough to cause damage to the tank,

Some A/F will make it to the black tank which should be enough to keep the drain valve from freezing same goes for the gray tank so leave that there.

Drain W/H before low point drains. Pump A/F thru (Black tank flush). No need to remove Tvs. Youroo!!

Thanks for all the feedback, everyone. I had never re-emptied the tanks in my older RV, either, but saw some in youtube vids advising it and, actually, I was surprised when they drained they got about 1/2 a gallon out of each tank. (But it was very pink so probably woudn't be an issue.)
Since we're going camping this week and my wife is bringing her sewing machine to work on some grandbaby dresses, I'm going to be seeing if I can either remove or make a bypass for the water filter. (There are a few hardware stores within a few miles of the park since it's very close to Denver.)
Youroo: Ah, I wasn't sure if I should put some A/F down the black tank flush...good tip!! (When I'm inside the camper, I'm going to look at all of the lines and see if there's any p-traps in there.)

I would leave a small amount of A/F in the toilet to keep the seal from drying out.
