Loudruff - I have read in other posts that at one time AS made the insert in other colors, including blue, orange and black. Not long ago I saw i thread where Inland RV had some black left. I don't think you can get any color other than blue from JD Saunders for $13. a roll as it is the "standard" available color now, but they may have other colors available. Try calling the #800 and talk to Dave Saunders. He was very nice, helpful.
PS - Did I mention that we have the 6.7 Minuet also (her name is "MINI". We measured and it looks like 1 50' roll will make it all the way around her. Good luck with search.
Chas - Glad to help. I would really apprciate your mentioning my name and that I did in fact post the #. He (Dave) was real friendly, and I loved hearing that "southern" accent again! We are transplants to Colorado (don't tell anybody!!!!
