Decals Starting to peel

Our decals on door side are starting to peel. Any suggestions?

I know there is another more recent post about this with another member, if I can find it I'll post it for you. Not sure what the outcome was, is it along the entire entry side or just in one place?

Found the thread, hope it helps. //heartlandowners.org/showthread.php/34765-Decals-Coming-Off
