Stripped screw holes in shore power cord access hatch

It it has aluminum siding, there's likely a wood backing. If fiberglass, I remove the screws and the hatch, rotate the hatch and re-install the screws. If fiberglass, drill pilot holes first. You'll need to recaulk or use some butyl tape. If you can get to the rear of it, you might be able to add a small scrap of wood for backing and screw into that - and use longer screws if needed.
