Thanks for the references guys, I will look them up. I'm hoping to reinforce this area solidly.
I've used some marine epoxy for now to cover up the hole. It's in a somewhat unfortunate spot, a fall could easily knock it off, as the material seems to be somewhat rigid and probably won't last the entire trip. Thanks for the tip with the screw though, I'll keep that in mind for a future field repair.
