Has anyone had trouble with water leaking with the back of the ext? Has anyone had a hard time cleaning the back of the ext?

haven't cleaned it yet, but also have had no leaks in the back. and i even sprayed water directly on the back to see what would happen and there were no leaks.

If you open the tailgate after it rains or after a carwash then it will leak water. The way it drains from the top, it runs right down to the side of the tailgate and water drains right into the rubber part of the bed. Water will then creap under the rubber mat and you will have puddles under the mat. I have to dry the bed once in a while with a rag. Hope this helps!

i've never had those problems. i've opened the tail gate right after soaking the back of the truck and there is no water anywhere.

If you lift up the rubber mat in the bed, there is usually moisture there after washing the truck. I usually dry that area with a towel about a day after washing the truck.

i've heard that before and i checked and i have no moisture. completely dry.

I get some water in the back, its normal. As for drying the back take the mat completely out leave it for a day it will dry out.

i guess i'm one of the lucky ones :D
