That is what sold the trailer for us during the factory tour. Seeing an actual household style duct along the centre of the unit, water lines placed inside that duct to keep them warm, and the lack of cheap tinfoil dryer venting just said this is the unit. For those that cold weather camp this type of treatment for fundamental services like heat and water is miles above all the other trailers we looked at. The more I am learning about our trailer the more I like it.
