Tacoma bed leaks bad

Thread revival !
My 2021 leaks too!!
Brand New ARE cap......I called to complain about installation and they said it must be a Toyota!

 

If you look near the cab part of the bed there are some holes between the bed liner and the actual bed. I did some dap in there and I have a small leak. I just put a bunch of putty in there today. Never really bothered me until it became monsoon season in California. I have a bed mat so most of the water goes underneath it and dried out the next day, but still hoping this works. I got lazy and did the flexi seal stuff. I should have orders butyl tape but rain is coming tomorrow again so time was if the essence. Haha.
I also was debating puttin a little sill along where it leaks to just deflect the rain. It really is just a small gap.

 

My ARE did too. The dealer told me afterwards "we don't do anything to seal it from leaking". WTF? Why did I buy a canopy. On other trucks I owned the dealer was able to seal them and they were always dry.

Anyway, I removed it and re-did the foam seal underneath and caulked/sealed the corners really well. I also removed the bed caps and sealed all around every hole and seam. I then put weather stripping along the vertical edges of the bed where the tail gate joins.

I got about 99% of it.

There is a video somewhere of what to do. I found the video helpful, and only wish I knew ahead of time.

 

What did you use?

 

Under the bed caps I used an exterior caulk called Big Stretch. I was able to purchase if from my local ACE hardware, but it is also available at Home Depot and Lowes.

I work in the building trades and have experience this caulk and the manufacturer's other products. It is one of the best imo.

 

So you basically make a gasket between the truck bed and the plastic cap for each of the holes? I am going to be doing this on my next rig (waiting for a 23 hence my interest) - did not do so on my 18 and lots of dust sifts thru so want to do that upfront.

 

It isn’t a boot dryer.

 

So, are we supposed to read your thoughts?

What cover? What is a cover? You have a tarp over your truck bed? Or something else? Is it torn? Broken? Not installed correctly? Does venus line up with uranus?
