I have been looking for a dash cover for my coach. I can get one in Perry at the rally with Shade Pro who does not have the pattern but will be there and they can measure and make it later and ship ...
DW made ours from some left-over dark fuzzy material she had on hand. Took most of a day to fit and make, and it is wonderful. Our dash is light colored, and when driving into the sun, makes it very difficult to see. The cover cures the problem, and looks nice also.
