Tonneau cover

Can anyone tell me how waterproof the OEM Tonneau cover is that comes with the 2016 tacos?

 

There are some threads on this; many have stated there are some gaps and leaks.

I am looking at aftermarket such as a retactable from gatortrax.

 

Thread Revive.

Does anyone know the Part number for the OEM Tonneau Cover?
Posting both the Long Bed and Short Bed Part Nos. would be nice.

I was able to find the exact truck I wanted with the hopes of buying
the cover later. And I had seen other threads say that the cover
might have a revision for leaks or something.

Thanks in advance!

I put the GatorTrax on my 2016 SR5. No leaks and it looks awesome!

 

I have the "Open Air" tonneau on my truck. Works wonderful. Nice for when I wash the top of the truck just climb up in the bed and get after it.
