Are there any 100% waterproof tonneau covers that exist?

[mike90]

Just had a Line-X quad fold hard tonneau cover installed. I was hoping no water would enter but there is a slow drip at the side that backs up to the cab. Nothing major but I was hoping it would be 100% watertight. Is there such a thing out there? Or are all tonneau covers going to let some water in?

It's referred to as a cap. They sit a little higher than a regular tonneau.

Unless you get a full truck cap or one of those one piece fiberglass covers that are hinged I doubt there are any that are 100% waterproof. I think they will all let water seep in from somewhere. I had a Gator soft tri-fold on my 11 Ram and that got some water in it. I now have a 21 Ram that I'm using a cheaper brand soft roll up cover off of Amazon and its way better about stopping the water but even that let's a little in. In both cases it wasn't bad enough to actually worry about even if I had anything of value in the bed

I have an Access Larado soft roll up on my ‘20 Rebel. No water. Had the same on my ‘17 Titan. No water.

Thanks guys for the replies. I feel a little better knowing some water is expected.

My Undercover one-piece fiberglass tonneau on my Gen4 never leaked. It was great but cumbersome when trying to haul a large item. The biggest problem I had with that cover was insects making dirt homes underneath the lip of it.
