You can put TC on any length of flatbed. You will need to manufacture some kind of front bumper, but securing the sides will be an issue as well.
Newer Fords are famous for taller cabin, so some TC require shimming, but flatbed elevates the camper already, so as long as headache bar will not to go above the cabin, you should have no problem with it.
For ties, I am afraid you are looking at custom stuff, but members who did it might add more details.
I had TC on steel flatbed for 1 trip and that thing was "walking" like crazy, so make sure you have good rubber mat.
