Mine leaked on the Bigfoot as well. I thought perhaps it was because I had the vent over the bed cracked a bit, with Maxx Air cover on it, and I was getting a vacuum from this. I closed the vent and didn't get as much water in for the remainder of the trip. Still got some coming in.
I put duct tape over the weep holes when the camper is on the truck now. It seems to have kept the rain away pretty well, so I don't know if it is a solution or not.
I am going to try the paper towel solution, that is easier to remember than adding the duct tape before the camper goes on the truck.And it doesn't leave the ugly sticky glue behind.
