Funny you should post this question. I just finished updating a post that I've out there since last August.
I was in need of decals as well. There is a sticky under
Repairs and Maintenance that has a list of online suppliers.
Rv suppliers and rv parts sources
Search for Decals. This site has decals that you can order.
Trekwood RV Parts
I had to have the front cap repainted on my camper. The body shop had a hell of a time getting decals. Keystone told them that the original decal manufacture went out of business and they couldn't be purchased anymore. I had my dealer order a set from Trekwood, but Keystone found a new manufacture and I was able to get the decals applied this week.
Hope that helps.
