Winterizing Questions

[silverta16]

New camper guy here, first winter. I have a Jayco 165 sport. I pulled the low water drains and drained all the tanks and the water heater plug. The lines sitll have some water in them. I have the camper in storage against the wall and not near an air compressor where I could blow it out. I found the 2 foot rubber hose mounted near the pump I figured was for winterizing. Do I just close the valves and use a gallon of antifreeze and let it run through all the lines? What about the black water tank, do you guys pour a gallon down or leave it dry? My fresh water tank has about an inch in it that I cannot get out guess it'll be ok? It'd have to be real cold I'd imagine to freeze and do damage. Anything else I need to do? Supposed to be mid 20's at night here in KY this weekend, kind of snuck up on me. Was hoping to do a little more camping this fall.

You put the hose in the jug, open the valve that is between the hose and the pump. Close the valve on the line coming from the fresh tank to the pump (image below). Insert hose in jug. Make sure hot water heater is bypassed by turning the appropriate valves (image below). Turn on pump. Open each faucet one at a time, hot and cold, until the pink stuff comes out then close each faucet one at a time. Don`t forget toilet and outside shower. Also open low point drains momentarily until pink comes out. If it takes more then one gallon turn off the pump and insert the hose in the second gallon. Pour a cupful or two down each sink and in black tank.

Ok got it done all went well. 1 question do you drain your black and gray tanks completely to drain the 2 gallons of anti freeze or leave it in all winter? I ran about a gallon of pink through the toilet and grey trains not counting what's stuck in the lines. Thanks

I always leave the pink in the waste tanks. A little moisture on all the seals just helps keep them working smooth in the spring
