2019 Coachmen Leprechaun Winterizing?

On my Coachmen Leprechaun 27QB the fresh water tank and pump are under the bed. There are 2 valves beside the pump that need to be pulled to drain the FW tank. There are 3 valves under the kitchen counter that need to be pulled-these are I believe the low point drain. The HWH is under the fridge. The bypass valves are there, close the 2 open ones and open the closed one. Go outside to the HWH cover and open the pressure relief valve then take out the drain plug. Then go back to the fresh water pump and unscrew the valve on the inlet side of the pump(the side the screen is on). You will need a fitting that will screw onto the pump(I had an old shower hose that screws exactly on the pump) with 2 or 3 ft of hose. Screw that onto the pump and place the hose into a jug of antifreeze. then turn the pump on, and go to each faucet and turn it on until each one(including shower and toilet) runs pink. Not too complicated. Oh, close the valves to empty the tanks before you run the antifreeze in. Gary
