Looked but did not see a thread on this.
Looking for a bed matt that will allow water to go through it and keep things on matt from sitting in water.
Dri-Dek® Mat in Stock - ULINE
This is an option and I have some of this on my boat. However, it's in 1x1 foot pieces that snap together. Hoping to find something that is one piece if available.
My bed is covered but some water still gets in and looking for solutions. Really do not want to go the garbage bag route.
I saw some 4x6 stuff on line but would like it to cover the whole floor if possible.

 

I just got a thick rubber bed mat and drilled a bunch of holes through it so that water can get to the drain holes in the bed. Works reasonably well.

 

Maybe something like this, usually used in back bar?

I would think the priority would be to find a bed cover that will truly seal out the rain and snow. And as the previous post suggested...it's easy to drill holes in a rubber bed mat so it will drain.

 

Check out a bedrug, might be great for your situation.

 

Rain screen material, like what is used for exterior walls in construction, might work. Unfortunately it comes in rolls much more than you want. Maybe you can go to a residential construction site and buy a scrap.

 

At least as far as tonneau covers are concerned, there is no such thing. Some do a much better job than others, but none of them are 100% dry.
