1. If these were done by Monaco during coach build you can wager that there is not a lot of complicated moves required to remove the panels. If as some have suggested they are glued or siliconed to the door why not get a 4-5" wide scraper and try working that in behind the decoration. When you do get them removed and re-in stalled be sure and clamp or somehow support them until the new glue/sealant sets up. 2.The exterior panel on the doors may be easily removable by removing one side or end of the old doors allowing the panel to be slid free to check for fasteners. 3.Call Monaco as they are still a few of the older hands there that can give you the low down on how things were done before bankruptcy and the sale to Navistar.
