Normally , yes, the decals , etc. are available for lots of them but supply and price is always a question.
Parts catalog here to get part number of the exact correct one:
https://catalog3d.winnebagoind.com/menu/Parts.htm
Look for the "graphics" section as you drill down.
Once on the graphics group, you can click and drag the drawing to show the exact part you want. Click it and it turns yellow and highlights of the part number, etc in the list at right!

Armed with that info, you can then do one of two things. Do a seach for that part number OR call one of the many Winnebago parts dealers for available parts and pricing!
WARNING: Set down before asking prices!
As further info, we could get the decals off with a cheap little buffer tool but it also left a major sun fade area which "required" a new decal to hide it!
Good luck on the chase!
