As you can see in my signature pic, I have an extra 6 x 14 ft added to the front ,with hooks , to add to the dry area and I also stake the corners down. /and always angle the awning a couple of inches to the front or rear(depending on which side of the campsite is lowest.)
It was a rainy few days at Algonquin Prov park...tarps kept us dry.
