Sorry about the 
I was looking at the V-10 and changed my mind when the price of gas
was going up last winter and went with the diesel for other reasons.
Do the V-10's really have that much problems with plugs ?
Or is it just poor maintenance?

The 3V modular engines (V-8 and V-10) made before 2008 came from the factory with a spark plug that was a bad design. They MIGHT separate into 2 pieces when being removed. Ford published a TSB for this. If the TSB is followed during removal and the spark plugs are replaced with the recommended 1 piece design, you will not have any issues,

Folks that had the 2 piece plugs in prior model years were changing them early in fear of breaking plugs off, which creates more work.With the 1 piece plugs its not necessary to change them until 100k...if you want. If it were me I may change them out after 4 or 5 years or 60k, again thats just me.
But I have the dreaded 6.0
so no spark plugs to worry about LOL

) If your truck does have them then I would probably want to try changing them sooner rather than later, the longer they're in there the more carbon builds up and the higher the tendency to sieze. It's a common problem so there's even a tool from Lisle that is reported to work quite well in removing broken plugs. First find out your engine build date and then decide what to do. If you do have them, post back and we can help more - there's a TSB from Ford detailing the exact procedure. If your engine was built after that date then no need to worry about them until 100,000.

No Hard feelings at all I like a good ribbing now and then....but the 6.0 doesnt scare me at all. If there was a gasser out there that could get 16mpg towing a 13k 5er Id be all over that.
I love my 6.0, have had great luck with this 1, the 04 not so much. 70k and runs like a top. My DD is a company truck with the eco boost and that thing is sweet too, but I need a 1 ton and the SD is paid for, would I love a new SD with a 6.7...oh yea
