How to remove decal?

Ok , this isn't about a Mopar but. I have a 2011 Work and Play Toy Hauler. I store it under a 41' carport but the morning sun hits the front of it and the decals are shrinking and discoloring and I figured I'd just remove them and leave them off.
That is if I can find a way to remove decals and the residue left behind. This is on smooth fiberglass gel finish.
Can anyone help me, "GET-R-DONE"?
