I think we decided. Not to trade it into ford would take too much of a hit.

We are gonna throw it at lease busters and if someone snatches it we will upgrade if not we will run it as is.
Dealer said it was no concern for warranty.

My only concern would be the mto.
Not as good as with the 3:31 for sure, but I think the motor still needs a break in period for improved mileage. Currently around 17 to 18 mpg.

But the truck is really peppy and fun to drive particularly in sport mode.
