Replacing decal stripes on camper

We used a heat gun to remove ours on our previous motorhome and then painted them back on. It was about ten years old at the time. Sold it this past summer when it was 15 years old and still looked great.

Do a web search for RV decals, graphics, or wraps.
"Beyond full sized RVs, trailers and campers can be wrapped as well to match their original design. Like RVs, the decals will often peel before any of the original paint shows any aging, so a simple custom cut decal job will restore the trailer or camper back to its original shape."
This is the link from the above quote . I know nothing about them, so this is not a recommendation.
