Hello and welcome to mol. I am sure some one else will be able to answer your questions better then me.

Kinda late for doing this but its pretty much the same as a boat besides not needing to worry about the engines and genset(unless it has a generator).

Weve got a small pop-up camper that doesnt have a head so Im not 100% sure how you would handle that on a camper.

On our pop up, there is a hose under the sink just for winterizing. I would say your camper doesnt have something like that but you could use the intake on the pump side. We just get a couple gallons of antifreeze, put that hose in it and turn the valve on for the hose and turn the valve off thats coming from the fresh water tank and turn the pump on. Then we open all COLD water valves till pink anti-freeze comes out. For the hot water side, we made sure it was drained then opened a hot water valve and let just a little anti-freeze in the hot water tank. You do not want to fill it totally up with anti-freeze since that would take WAY to much antifreeze and you would never get it all out come spring. On ours, its easy to by pass the water tank once weve made sure a little anti-freeze is in it by taking the inlet hose off along with the outlet and connecting them together. Then you can open all the hot water valves till pink anti-freeze comes out.

For the fresh water tank, we have a gravity fill so we just poured what we thought was enough to keep it from freezing.

Make sure the batteries are all ok on water and are fully charged.

We used -50F RV/Boat Anti-freeze which is ok for the environment. DO NOT use automotive anti-freeze since it will kill you and can harm the environment.

Again, ours is just a pop-up camper so Im sure yours requires much more work. It would probably be best for you to get on some camper forums and search for winterizing to get an idea.
