I hear you. A little while ago the company who made the Sunline tire covers had a bunch left and liquidated them. They are all gone from there now, because a bunch of us bought them all up...
I think a few dealers still have some left, like Martin's Camper Sales in PA. But getting them to sell parts by credit card and ship them out is another story. I thought I heard another dealer in MA had a couple left too. Might have been either Dufour's or MacDonald's.
The 2006/07 style would be different from the OEM style cover for your coach. Yours originally was like your big decal on the back. The tire cover wasn't a shade shifter decal though, it was a screen printed purple sun one.
One option you have is to contact some people who have trailers for sale and see if they're willing to sell the one they have on it. Some people probably don't care, as long as they have enough $ to buy a new one and for their time. Insurance auctions are another good option, like
www.iaai.com. I think they're willing to do that if the trailer really is a total loss for use as a TT. I remember one a couple years ago I think Kitty called to check on. It was almost all burned to the ground, but it had a tire cover and hinged LP cover on it, but it turned out they were both melted a little.
Another option is I can send you an image, you could get a white tire cover, and take both to an embroidery shop and see if they could stitch it into the cover. But get your cover soon and lay it out inside your house, because the way they vacuum pack it, it comes out of the box very wrinkled.
