Decals are cheap and easy to replace. Just order some new ones and get her done...Anybody's guess as to why they won't stick. Some say not to wax them, others say to protect them with 303..I don't wax or put anything on mine. They're doing just fine. Once they are removed I would clean the side off with some automotive wax and grease remover, wipe that down and get it nice and clean and put the new ones on. Spray the area with a light soapy water mixture and spray the back of the decal with same. This will allow you to move it a bit and get the proper placement. Rub it down with a plastic squeegee or even a credit card, wipe off the water and let it sit and dry. Call Heartland customer service and they will set you up with new ones...Don
