The plug problem was on the 5.4 liter motor. If the owners didn't change them at the recommended intervals, carbon would build up around the threads and when you went to take them out they would break. When they broke a special tool was required to take the remaining piece out. Access on some of the plugs was so bad that removing the whole cab was at times required.
Any other motor in a relatively new Ford shouldn't have that issue.

The spark plug issue was on the 04-08 models and even then I believe they fixed it on the 08 if I'm not mistaken. The 2010 shouldn't have that issue.

I didn't have to remove the cab on mine, but I did have to purchase the tool. Some mechanics wouldn't even consider changing them, and others that would wanted $800 for the job. I broke off 4 out of the 8 plugs on mine, and used the Lisle Broken Spark Plug Removal Tool to remove the broken plugs. Was a pain and took a few hours, but was not especially difficult.
ETA: I received a recall notice in the mail regarding this issue, and it reimburses a percentage spent on the repairs if they cost over a certain amount. The minimum eligible was $300 but since I spent less than that I was not eligible.

My understanding is that replacing the spark plugs on the newer f-150’s is fricking nightmare. Anybody paid to have it done? How much?

I had an '06 F-150 with 115k miles on it that this happened to a couple of years ago. I took it in to get the plugs changed because it was 'missing'......my mechanic looked at me and grimaced, and he gave me a price assuming that everything went as it should (which he said is unheard of) and a price assuming that a few of the plugs broke off in the block and had to be extracted with the special tool (he said that this is what I should plan for and that cost was about $900, if I remember correctly).
He calls a day or two later, and as it turns out, I have the worst case scenario where the bottom half of the plugs are completely seized up and the extraction tool cannot get them out........which meant that I was going to have to get a new motor. And when I say new I mean new....because we couldn't find that type of motor at a junk yard or anywhere because there was such a high demand for them, due to how many people this had happened to. So by the time it was all said and done, I was looking at spending $4,000 on a new motor plus the cost to put it in, all because of some damn spark plugs.
I actually got something in the mail here recently saying that Ford has settled a class action lawsuit on this matter where they will reimburse anyone that spent over a certain amount on this issue.

Were these plug problems on the Triton motor only...?

2010 doesnt have the broken plug issues anymore.
Vehicle manufactures use iridium plugs these days that can reach 100k pretty easy. replace with iridium so you can retain that mileage without having to swap.
If you went to a copper plug you will want to change every 20-30k

I question your mechanic. The "grimace" you said he made should have alerted you to walk away. Given where the plug shear plane is and how the tool works, they will come out. It's a tool made especially for this purpose and application. I talked to a lot of mechanics before I removed mine, and most of them do not even want to touch them because of the perceived difficulty. Is it time-consuming and and a PITA? Yes, but they will come out with the tool and patience.

There are absolutely situations in which the plug will not come out. It is the worst case scenario, but it can happen and it has happened to a ton of people. There are accounts of it all over the internet.
I trust my mechanic......that doesn't mean I don't question him, but I do trust him. He grimaced (or maybe 'winced' is a better word to use) because he has done a lot of them for his customers, and he is used to them being pissed when they find out how much money it is going to cost.

The Ford design makes it easy to snap off into the block, which is why you might want to let the dealership do this. I've heard some gripes that they are charging unreasonable amounts for this fairly simple maintenance task for those particular engines unfortunately. I think it was for V8 Fords only.
I didn't replace them on my 2007 Silverado until around 160,000 miles. It's an easy task that can be done at home or completed cheaply by whoever you pay to handle maintenance. The ones built in the last 15 years or so have coil packs and are very well sealed. They last much longer between changes than on trucks and cars from 20 years ago.

Why didn't he remove the head and take the spark plug out or replace the head? Replacing the engine is nuts.

I thoroughly reviewed several F-150 forums prior to tackling this job myself and do not remember coming across this situation. If there was even a chance of me having to get a new engine, I'm sure I would not have even attempted it (and I do all regular maintenance and most repairs myself).
Can you post some links to some of these occurrences? I'm truly interested to know how/why this happened from a technical perspective.

Prior to the Ford/Lisle Extraction tool being made. Ford's recommendation was to remove the head to extract the spark plug or replace the head.

5.0 is easy. Did my 2011 a few months ago.

The show I was listening to about this said that will usually work, but sometime the whole cab has to come off to change the motor. I would assume it sheered below the head or it must be certain cylinders.

From what I remember, the bottom half of the spark plug was so seized up that the plug (or a part of the plug) would break apart before the plug would come loose, and it would fall down into the head or something like that.....seems like a piece of the plug was porcelain or fiberglass or something and it would crush it before it came loose.
I can't remember exactly, but I do know this.....instead of putting a new engine in it, I called my buddy who owns several dealerships and got him to find me a truck, and then I traded my truck in and just let his mechanics deal with all of that stuff.....and they did exactly what my mechanic recommended to me, which was put a new engine in it.
I also called a couple of the local dealerships to ask them if they thought they could get it done.....and of course they said that they could usually get it done, but they did acknowledge that they had seen situations where the plug just couldn't be extracted.
When I get home tonight, I will look and see if I still have any of the links to the accounts of this type of thing happening to other people.

The F150s with gas engines can be removed without the cab coming off.
