Now that I have a significant portion of the belly pan done, I'm going to go back and adjust a few things.

1. Install a full-width front section. I skipped this originally because I didn't see how to attach on the outer edges of the bumper. I think I found a way to do it so I will play with that. I might end up doing a two piece driver half/passenger half so it's easier to work with.
2. The rear edge of the wheel well is still open which allows air to move down the vehicle *above* the pan, defeating the purpose! There's only one spot to attach a piece of something there, so want I am planning is to slit and fold up the chloroplast. This will force the air down and across the bottom of the pan.
3. I need to get a gopro and watch the pan at speed. I have a feeling the pan is reverberating. I will need to figure out a way to install more attachment points. I think I have an idea that will work, I'll use some threaded rod and some accessories to "drop" the attachment point from the frame up high to the pan closer to the ground.
4. Better integration of the front pan, the stock pan under the oil pan, and the two mid-section pans to keep better air attachment across the whole system.
5. I'm not sure how to put a pan further to the rear of the truck. I'm starting to get into the rear end that has the muffler, gas tank, axle, differential, spare tire, etc. We'll see if I can make something work back there.

Generally, fastening sheet materials, you have the edges and the field.

One or two fasteners in the middle might prevent those from becoming water reservoirs. At least some small drain holes.

Do you hear a drumming sound?

No, but then again I probably wouldn't be able to with the hum of my cupped tires! lol

But I can very easily push on the middle of the board and it snaps back. Unfortunately, the frame crossmember is high so no real attachment point without getting more parts.
