OP here.
Thank you all for some excellent suggestions...
Flex mend looks great! So does screwing or riveting in an aluminum strip. Gorilla tape and goop is a strongly possibility...
I will be down to the camper in the next week or so to take a closer look and fix it.
All I need to do now is wait for this dusting of snow to melt so I can comfortably crawl around under the camper.
75 degrees yesterday, snow today. You gotta love spring in the Midwest!
Tent camping this week to do some trout fishing in the Ozarks! Can't wait!
