I had that happen to my last Class C (not a Jayco!) but the doors are similar across all lines. I ended up using screw inserts, the kind you use to install screws in drywall (sheet rock) or plaster walls. I actually coated them is two-part epoxy prior to tapping them into the door. I let it cure overnight before reinstalling the screws.
Held for years until I sold it to buy my current Seneca!
