1. Several rolls of plastic wrap around the car and the trailer. I recommend Saran wrap.
2. It's a Ford. Who the hell cares?
3. Get a tire trailer and don't worry about tying down the car.
4. Use the factory transportation tie down points. Run the straps/chains/baling wire/duct tape/bubble gum/etc to whatever points are convenient on the trailer. It really doesn't matter whether the straps go fore and aft or crossed. That is really a function of the size of the trailer.
