Greg, that doesn't surprise me that you had to upgrade. The 13.5 Penguin didn't cut the mustard on my 27' Safari when the temps hit the mid 90's or above. That's why I upgraded the Classic at build time with the 15K unit. I've never regretted that change.
My dealer has a cover in stock. I called yesterday and he noted that they keep a supply of these on hand. Apparently the cracking is a well known problem. Interesting that this is the first time I've ever had this happen on any trailer.
I'm not sure what this shoulder is that you are describing. It will be interesting to see what the replacement cover is. I noticed that the 15K Penguins have a couple of different covers. Apparently Duo-Therm did a design change late in 2003. Silvertwinkie's Safari was built about 60 days after my Classic and his 15K shroud is different from mine.
