Door drain?

[Kenfuzed]

I'm reassembling various parts of my truck after having it painted. While looking at the doors in prep for installing all new door seals I noticed that there is no drain in the bottom of the door. The anti-rattle felts I bought for the windows don't seem like they would keep all water out that runs down the windows. Wouldn't this just pool in the bottom of the doors? Has anyone put drain holes in the bottom of their doors?

I will be relocating the truck to Tampa next year and it will see it's share of summer rain so trying to prepare now.
