IMHO I don't understand the absolute need to replace the "exact" same decal if yours have been discontinued. Only you and your MH know what design was on your RV in the first place! :B
If there is fading you can't buff out most of my friends just buy in stock decals slightly bigger or wider in design to cover it and put it on.
I run a graphics shop and can recreate many of the RV graphics and decals. While I do not install them, I can produce replacements that are very close to the originals and send them to you to apply yourself...
OP's first and only post is for the sole purpose of advertising his company. Which is against forum rules.
