Winterizing 210 RoadTrek for winter use (14 degrees)

I don't think blowing out the lines with air will hurt anything, just Roadtrek covering their butt. Having said that, It's my opinion that blowing out the lines is not a good way to winterize a Rt, you are taking a chance of not getting water out of the low points. If you do decide to use air don't go over 40 psi, and use an oilless compressure. jmo

My Roadtrek 190 has the same interior tank for "winter use" and yes, the interior tank can be used down to 14 degrees for three days as long as you have heat on inside the coach 24 hours a day during those three days and don't drain into the grey or black tanks because they are outside and unprotected from freezing - as is your macerator pump.

Also Roadtrek says not to use an air compressor to blow out the plumbing. They say that it will be damaged if you do.

Unless you are heading for warm weather and it will take just three days to get there, winterize your Roadtrek. The procedure is simple. Follow the instructions in these two articles on winterizing a Roadtrek - this applies to your 210 the same as it applies to my 190. (I am about to write a third article putting it all simple and step by step.) Take no chances. The cost of repairing burst plumbing far exceeds the inconvenience of winterizing and learning how to travel in your Roadtrek without any water.

You can protect the city water inlet and connections from there inside by pumping antifreeze through with a antifreeze hand pump, sold at most RV shops and some boating stores,that connects to the city water connection. It is fast and easy.

I think they mean you need to blow out the water in the fresh water lines with a air compressor.
