On my 93 coach it looks to me like they used double sided tape in addition to the screws. Since it is not structural I think you could get by with tape for mounting auto trim as Forest suggested. In addition, if you also wanted to keep the screws you might want to consider putting Rivnuts in the holes as they are less likely to strip the threads compared to sheet metal screws.
