I am a new RVer, and would like some ideas on how to prepare my motor home for winter. I understand they have special anti-freeze for RV's. I am not quite sure how you get rid of most of the water in holding tanks and water heaters etc. I know how to drain the 2 main tanks, but I understand you dont get it all this way. Any help would be greatly appreciated. Thanks, Phil

Kind of let us know what year and type of MH you have, and someone out here will have one just like it and will know how to set it up for cold weather.

Open the drain on fresh water tank.
Open drain and pressure relief on water heater.
Open low point drains.
Open every tap (hot and cold) and flush toilet.
Take connections loose from ice maker and let drain.

Drive arround for a while. if your black and gray tanks aren't empty, dump them.

Now you can ether attach an air fitting to the water supply connection and close all the open valves then open one at a time while you blow air thru the lines. or buy a plastic hand pump and some RV antifreeze and pump it into the system, opening each tap one at a time till you get pink antifreeze.

Ether way be sure your pee traps, toilet and black and gray tanks have a little antifreeze.

Sounds like quite a project but isn't realy that bad. mine takes less than an hour.

In addition to this great info, here are some links that will help. I did mine last year for the first time. It's really simple. Take an hour or so.

I live in my Dynasty in Carson City, and also camp in it in Nevada, Idaho, and Death Valley throughout the winter. An alternative to winterizing is to keep it ready to use. One thing that helps is having the furnace on. I do not know if you have solar panels or electric hookups but if you do, you can leave the furnace on a low setting. When it gets cold enough to worry, the furnace kicks in and warms things up. I do not drain anything and have had no problems. Plus I can just unhook and drive away. If you do this, you must remember to unhook and drain or heat your water line. Just a thought.

I have read most of the threads on winterizing and there are a couple of things that I do not see memtioned. If you have a washer/dryer it must be winterized and don't forget the ice cube maker and the undersink water filter if so equiped.

If I have forgotten anything please don't hesitate to add to this list because I'll probably be the one to forget it.

To add to all of the other suggestions, I store our coach on a tilt. This will allow all water to run off of the top where there are a lot of openings to ooze into, freeze and expand.

I also leave the roof vents open, (they have covers) and run a small fan on low to keep the air moving. If you seal it up too tight it will hold moisture and create odors and other problems. The fan on low is like leaving a 40 watt bulb on, not too expensive.

I also use 10 gallons of rv antifreeze to winterize, about 2 gallons for the lines and 8 gallons for those weekend trips to visit family or the ski resort.

Pee-pee only rule applies. LOL.
