You can not remove 5th from a f450 it is part of the package. I ordered in June and got a vin February 1st for a March build and got bumped two times and I am at Aril 4th now. I ordered a f450 limited with spray in bed liner, wheel well liners, safe, fx4, rapid heat, second alternator, trailer cam setup, factory fifth to tow our trailer. The waiting is definitely frustrating especially when I saw a post on FB from a person who ordered the same build and color in December and he already has the truck.
