Short answer: They have a history of not working well in Ford trucks.
Why? I have no idea.
Wish I had more specifc info, but that pretty much sums it up. Stick w/ Motorcraft is my suggestion.

Which bosch plugs are you thinking about running?
I've ran platnium +4's in 3 different vehicles including the truck I'm driving now and saw a noticeable improvement in performance. The first vehicle I had was a '91 300zx and my retarded@$$ didn't even have the #6 cylinder hooked up before I took it for a spin and it ran even better than before (It was really fun to drive when I had all 6 cylinders banging away
Next I put them in a '94 f-150 with a v8 and and saw an improvement there too.
My truck gets really good gas mileage which I attribute to those spark plugs. It's 120 miles from the oil rig I work at to my house and I only use a quarter of a tank of gas =) sometimes less than that.
I guess for some people they work and some they don't. They've never disappointed me in my endeavors.
If you're not feeling lucky though just stick with the motorcraft/ auto lites or NKG.

I put a set of Bosch P-2's in a few months back (before joining this group) and wanted to make sure they were'nt gonna damage my engine, If it's just about drivability, I haven't had any problems yet....(knock on wood)

Me too actually.
Maybe they changed something in recent years that makes them more compatible with Ford trucks.
Regardless, glad to hear anytime someone has good luck with their truck!

when did yall change plugs?
I just pased 80k yesterday, gonna do my 5k oil change today (I use synthetic) I have done 'some' tune-up work on my truck, butnot plugs and wires, havent had a problem at all...basically...the only things on my truck that arent stock are brakes, tires, belt, waterpump, altenator...and the pcv? valve I think.....and just about every single body panel has been replaced at one point or another....including the entire bed and half the cab

Bosch Plugs
The reason you DO NOT USE BOSCH plugs in any motor is because if your motor is older and has a little blow-by the oil will cause the Bosch plug to explode and the ceramic material at the bottom will score your cylinder walls.I learned this the hard way.............Motor still runs but the blow-by now is so bad, you can't even drive it.

I agree 100%. Ive got the 4.6 in my mustang and only down side ive noticed with the bosch plugs is that after a few months they get pretty rough. Definetly likes the nkg's more.
