2019 6.9 box

While installing my weather tech bed liner I noticed that you can see right thu the gap where the bed floor meets the sides of the bed, Granted this is my first Ford in prob 15 yrs but when did this start, can it be that expensive to run some of that epoxy chaulk in there? Maybe it’s for drainage, hell I don’t know,

It's by design. I checked several trucks on the lot to see if mine had an issue before I took it home haha

Yes, very big gaps. Not great when you live on a dirt road . . . . Got a tailgate sealer kit.

It's partially do to the forming limits of the aluminum. Aluminum can be formed to make the gaps small to non-existent, but that would greatly increase the cost to manufacture. The aluminum would need to be annealed (softened), then formed, then heat treated so make stronger/stiffer. The limits to how strong/stiff aluminum is and how much it can be formed/bent before it breaks or cracks is a smaller window that what can be done with steel.

I would have thought the gaps would have been filled and drains been made, but i guess it was lost in the cost-benefit analysis. If I dumped sand in the bed, I wonder how much would fall out. Some of the gaps do seem on the large size.

I was surprised how much water made its way into the bed when driving around. The rear wheels kick up a good amount that makes it in in the gaps between the wheel well and tailgate. I wonder how much crap is getting trapped under the Bed Tred liner I have? Granted it's aluminum which won't rust , but once the paint and primer are worn away it will oxidize. It will be interesting to see how the aluminum holds up over time compared to steel.

Line-X will seal it all up and not allow oxidation...Makes the bed stronger also.

Not quite......
Its to do with the tolerances and spring back of the material used which is accounted for in the initial design and tooling. Not because of the forming limits. In mass production you need the tolerance stack to offset any variation in the build process so the parts will always fit. It is never a net/net build.
I had mine line-x and then filled in where there was a small gap with roofing sealant (black obviously) . With my cover its dry and not dusty.

Thanks for pointing this out... did not notice when looking at trucks at a couple of dealers back in Oct. I will have to see what mine looks like when it comes in... Feb-Mar, just ordered it last week. I also live on a dirt road, so I also want to keep the road under the truck not in it. Ordered a Truxedo cover on Black Friday. Any other ideas on sealing the gaps?
