Hello All,

First post so let me know if this needs to be placed elsewhere. Ok so here is my problem:

Ive had this truck and topper for some years now and have just been putting up with the amount of water that gets in, well now I am sick of it. I have narrowed down that the water is coming from the tailgate area of the topper and soaking the carpet liner and dripping all over the corner of the bed. Also ONLY on the passenger side.

Photos are below to show that the water is not running up and down my bed rails as they are dry EXCEPT for the parts that the carpet liner touches. Only thought is that the water is coming in the corners of where the topper window meets the tailgate and soaking the carpet. Anyone have any answers or experience with this?

One of the pics shows where I tried to make a barrier with butyl tape and extra weatherstripping.
