I will take delivery of my new Expanda in 3 weeks and have some concerns about the Clear Water hoses used in the Expanda. My previus experience with my Jayco Swan is that the clear hoses started going green after about 12 months. Has anyone had this problem and is there a solution or recomendation of any sort.. Is it best to replace exposed Clear Water hose or perhaps cover with tape or paint in some way? Any advice welcome.
