Hi there...just wondering what happens if we winterize our coach put it in storage and leave the antifreeze in the motor home system for an entire year knowing we won't be using our coach for the next year since we have some personal issues to attend with.

Will the winterizing process still be effective for the following winter season or does it need to be changed?

So you know, You can't use any of the plumbing till you de-winterize your coach which I'm sure your aware of and it should remain effective for 2 or more years

I would suggest however you use the "Dry" method on the supply side (Blow out the lines with air) use "pink stuff" in the traps, You may wish to re-fill them with new pink stuff down the road.

Don't forge to fill your diesel tank and treat it for algae. As above, I would consider the dry method, but as a precaution, you may want to consider having a professional prepare it for long term storage.
