Winterizing 189

I have a new 189 and it does not seem to have a dedicated hose line to use near the hot water heater for winterizing.  The videos I have watched all show a hose line with a valve for use in using the pink stuff in winterizing.  Has it been eliminated, or is it in a new location? 

I just add the antifreeze to my fresh water tank after all lines and tanks have been drained then use my water pump to pump antifreeze through lines starting with the farthest away faucet and working my way toward the pump.

Doug, I have a 189 and I made up this diagram for someone else. I just did mine this past weekend. The valve that's used to draw antifreeze into the system needs to be turned from the position I show in the picture and you need to place the end of that hose into a gallon jug of antifreeze. I hope it helps. Message me if you have questions.

Thank you.  I didn't lift up the rear plywood panel under the bed to see the valve.  I was using older images that showed the valve under the front panel.  Thanks for making it so simple!!!

I am getting ready to winterize my 189 and really don’t want to be moving the mattress and turning valves. That is the way we winterized our old pop up trailer before we bought our Rpod. So if I just pour a couple gallons of the rev antifreeze in the fresh water tank and turn on the pump until the pink is coming out of all the faucets I should be good right? Do I need to let the water heater take on the antifreeze as well then turn on the hot water faucet until it runs pink too?
