If that were to happen to me I'd probe the hole to see if there is any reinforcement where the screw was installed. If so, I'd pull the old screw and go to the local fastener shop (NOT a big box store) and buy longer screws. Fill hole with a piece of dowel with some Gorilla Glue. Re-drill and reinstall.
If it was just a matter of too short a screw I don't have a lot of confidence that a Dealer would do much under Warranty than just replace the same screw after filling the hole with toothpicks (yes, I've actually seen that done).
FWIW, if this happened just sitting in the Driveway be sure and secure the awning, even if you have to tie it back with a rope wrapped entirely around the RV, before towing it to the Dealer (if that's your choice).
