Should have made it more clear, it's nothing new to racers and engine builders. To the general public they have no idea...
Just trying to state don't think this is a new rebel thought process on engines.
I've used this method on all my vehicles, and I've arguably have one of the fastest if not the fastest 2004+f150 on a factory long block(hoping to hit high 11's in the 1/4 mile this fall in good air). Still make 19+mpg with my 5.4 and over 460rwhp on pump and 500rwhp with race gas.

*edit*
highways are fine, but you just cant just get it up to speed and hold it there. Which on the highway is very annoying.

I'm sure Ford just goes on the Internet and rounds up their favorite ideas for break-in.....
Or they build it and give advice so that you will be happiest with your new truck, and they will be less likely to have to fix it for you. The point about the entire drivetrain breaking in is valid. Gears can score if abused before they are worn in.
Beating on a bike, which generally never "wear out", as they are crashed or destroyed before their time, is a different story, and the extra couple of hp you might by beating on it could be a bonus. Just vary the speeds, and definitely do a little wide open throttle at passing speeds to assure go engine break-in, without stressing the rest of the truck.
Same reason they recommend not towing, and they Internet engineers should quit dispensing silly advice.

I agree with your statements about the gears and varied speeds. Ford says what they say in the manual for a reason...
I would say they know more oval all about what's right for there trucks during break in than all the opinions good or bad on the forums.
If you read the manual it says the truck needs little break in, vary your speeds and do not pull a trailer for 1000 miles.
I get the feeling this is to make sure the drive train is good and broke in before pulling weight behind the truck (this is realy a no brainer and a safe aproach)
Yes Ford is covering there butt here
but there also covering yours, more than likely 500 miles is enough . Go with what Ford says, they built and engineered the truck.
I am sure an enternet Forum Engineer/Mechanic will correct me and say Ford is wrong and there way is better.
Take Care All,
Bill G

Running an empty truck at WOT is very different from running WOT with 11k lbs in tow. Just go drive the thing like you would normally drive. While I wouldn't recommend bouncing it off the rev limiter, a few good spirited accelerations are not going to hurt anything.

Metallurgy is MUCH different then it was 20-30 years ago... Anyone remember "breaking in" a camshaft(2500 rpm for 15-20 minutes), valve jobs every 20,000 miles, etc.? A lot has changed since then..
Ford says it their way, varying speeds slowly etc. because they can't "legally" tell you to go romp the hell out of your vehicle on public roads.... If you ever get a chance to hang out with the FRPP/SVT guys that go to the race tracks they will tell you exactly what we are telling you..
Honestly the methods are EXACTLY the same, it's just the "racers" method is much more aggressive.
Cruising the same speed is one of the WORST things you could possibly do on a newly built engine.

A comment on the highlighted area: You are right, they can't legally tell you to "drive it like you stole it", but if that was the case, wouldn't Ford just say, "There is no break-in period"?

You bring up very good points, especially about engines being in a totally different league than they were back in the day.
