If you are willing to spend a bit of $, I would guess that your decals are available for replacement. I replaced the "Horizon" decals on my Itasca Horizon, which were peeling off. Go to winnebago parts.com, which is actually a company called Mobility RV. They buy all the leftover decals from Winnebago after each years production run. Give them a call to see what is available.
My decals we less than $20 apiece, but as I recall the stripes are quite a bit more.
