what about rain getting in all the time? does it just blow out over the bed when the truck is ran? i like the cleanliness of the rings on the cover, what did they charge you to cut up the cover?

I drilled a hole in the lowest point in the pipe under the bed to let the water out. It still blows chit out of them when you start it after a rain though. I cut the cover myself with a razor blade.
