I would first ask Denny for a new decal with backing. I'd then remove the decal from the door. If you ever want to sell the camper, someone might want that cool Jackson Hole decal affixed tot he door.
I left my decal attached to the door. We consider Tom and Celeste friends and wanted to help sell the camper in the southeast. We have been approached by dozens of folks wanting to know what kind of camper we had in the bed. I would always tell them to take a picture of the door and check out the FWC web site.
Now that Tom and Celetste are retired and traveling in their new Super Duty with a Hawk Woolrich in the bed and an Airstream in tow, I'm likely to pull the sticker off my door. I still think FWC is a great company, just need the space for other stickers.
