Bed “drainage”

[Maverickman74]

If you do seal that gap seal it from the bottom and top otherwise that salty slush will still be in the gap just not in the bed. That is until it rots it and you have no bed.

The Maverick has bed drainage - How do I know, because They Drilled through my bed and hit my fuel tank in all six spots!

Oooops

I still don’t know where all this bed rot issue comes from. If the slush I’m talking about is not allowed to enter from below, how is this increasing bed deterioration? By reducing the amount of water that comes in, by eliminating one of the infiltration points (not fully, I mentioned leaving typical wrap gaps by the cab) wouldn’t that reduce the likelihood of corrosion? Why let more in?

The side wall to floor gap has been going on with Ford trucks for sometime. My 2018 f150 is not sealed here and no water enters my bed from the underside. I have the factory spray in liner in it and the gaps are still there but probably smaller than with no SIB.

If you have never had an issue with rust under a drop liner, you my friend are one of the lucky ones or you have never removed the liner to see the bed under it. As for other trucks not having drains. All trucks were engineered with them. The older trucks they were small and plugged easily. I would guess this is the reasoning behind the extra drainage on the newer ones.

My Subaru Baja is a unibody truck with drain holes in the bed. It's NEVER been a problem in any regard. You're wasting brain cells on this.

Factory SIBL leave the gaps along the side. I worried about road spray getting into the bed and spent some time looking after a trip. The only water intrusion was from the tonneau and it was not very much. I have an old living room carpet cut for a pad and it was only wet from the top by the tailgate.

Help me figure this out. Every truck I’ve owned did not have drainage in the bed. The bed to sides are welded and sealed. The trucks I had that did not have covers would drain after the rain when I drove away, a waterfall would come out of the tailgate. That’s normal for all trucks, why is this one different?
What’s stopping me from sealing up the “linear drain” around the perimeter of the Bed? Ive need through a few snow and rain storms (and car washes too) and found water or snow in the bed where I’ve never had in previous trucks.
Don’t get me wrong, I do not think it’s supposed to be sealed 100% but this drainage is so different than any other truck I know of, and I don’t see a reason.

I know I am responding to an old post. I read the old posts and threads related to this. None mentioned debris lodged in the crevice holding moisture and causing rust. I hauled some plants from the nursery and all kinds of planting mix that spilled out of the containers lodged in the crevice. I had to use a dental pick to get the stuff out because a pressure nozzle and water didn't do it. After experiencing this, it seems that debris lodged in this area is more likely to cause rust than filling the the 4.5 foot long X2 crevices with black automotive grade non-sag body caulk applied with a manual caulk gun.
