I held the leads in two different spots, once on lead post to post and once directly to the bare cables, I get the same results both ways.

Voltage just prior to cranking
Voltage drop on crank
Voltage immediately climbs after releasing the key

I just don’t understand how either of the two batteries I’ve tried hold charge fine, start, run and crank other vehicles fine but has such a significant drop on this ford? I was iffy on the original battery also, put the new one in from my daily and still same business, running the battery in my daily driver at work as we speak. And have no problems with it even on 10 degreee mornings.

No they don't hold a charge fine, not according to your Volt Meter.
If they did, the would be well above 12volts.
Also, they wouldn't go below 10-11 volts, and your cables would start smoking.
Is your engine seized?

What’s causing this? I can let it sit for a while and it’ll crank semi-fine for a few rotations and pulls down to 9v while cranking but then it turns to this.
the battery was fine in another vehicle. Could this be a bad ground cable? I believe it may possibly start if not for this

Is the engine flooded?
With all the cranking you've done, you could have over heated the starter.

I didn’t necessarily have intentions to; I have a third battery at home I was going to use to confirm. I have tried 2 different ones and still get basically the same story. Seems odd it would draw both batteries down so low. I guess it’s possible they’re both a little weak, just seems unlikely.What’s your opinion?

I was only questioning the statement about buying a new battery and not having them load tested first. Batteries aren’t cheap.
How old are the battery cables? Is there corrosion at the terminals? Did you or someone else install those temporary terminal ends on one or both cables?

If by temporary terminal end, you mean one like the image below then yes this is on the ground side.
when the truck was running and driving, I got a no start heat soak issue where after driving the truck would barely turn over. After sitting a few minutes it was fine. Assumed it was the starter but I replaced. Wondering if this isn’t the issue I’m having now. Thanks
