Sorry fellas. We decided not to get the 150, so I haven't checked this post for a while.
Here is the TSB from Ford-Trucks.com.
Plug Removal Technical Service Bulletin
It details the plug removal procedure. I know this is a problem, but I talked to a couple of different people about this and the trick is to let it sit in the garage to cool down for the day. Then at night crack the plugs loose and shoot each one with Kroil. In the morning, gingerly remove them (follow the TSB). Some recommended anti-sieze...some not. Either way with the number of miles on the pickup I was confident that I'd have no problems getting them out.
I checked mileage with pencil and paper. I had the pickup for a week. I checked it twice over the same route using the same gas station, same pump...13 mpg. I know this is low and I assume it was due to the cold weather, but that's even bad for cold weather. It was flat, no weight, no trailer, just my wife and I. I think I could have explained 15-16, but not 13
I would have enjoyed adding it to the fleet, but if Momma's not happy...
Thanks for the replies. We still haven't found anything. Still looking
