Waterproof tonneau for Gen 3

Hey, I am new to TW and am looking for recommendations for a tonneau cover. I’m wanting a hard cover that is extremely waterproof. Please help or direct me to the right place. Thank you!

 

BakFlip MX4

 

Undercover Elite

 

I have the backflip G2. I keeps things fairly dry, however I would not say it is water proof. For example, I would put my suite cases and my golf clubs back there but not my lap top if I was driving through a heavy down pour.

 

I don't think any tonneau is waterproof. Even my old Leer shell, I had to silicone the seams to get it totally water-tight.

My OEM tonneau cover actually does a pretty good job. As well as my old Bakflip G2 cover.

 

Mx4 definitely does not come "extremely waterproof" on a 3rd gen like OP wants. There's basically entire thread that helps you make it become more waterproof. Mine leaked like crazy.

Certainly not the OEM! Leaks like the Titanic...

 

Truck Covers USA hands down... you punch 3 holes in the composite on the sides of your bed and run drain tubes which may freak some folks out but it's a very clean install. It's a heavy-duty rolling tonneau that can support 500lbs on the cover itself and you can buy it with prewelded Yakima tracks for crossbar / cage / RTT setups if you so desire. Love being able to lock up all my stuff securely in dry storage and still have the realestate above the cover usable for bikes, paddles, kayaks. Transformed my truck
