towing strategies

You are asking about how to tow so many different types I have to ask whether you are starting a towing business. If you are there are better sources of information. For the individual the single best source is the owners manual for the car in question.

Check the vehicle owner manual.

flatbed

That's all I see any more with passenger vehicles. It's too easy to damage or mar something on a hook. Once the vehicle is on the bed it's safe. Even the actual towing process is safer without dragging one vehicle. Accident vehicle towing is a big part of the business too and a flatbed is the choice.

No, more like I realized I have no idea how to safely tow an AWD car that a fellow may need towed. Isn't it better to have knowledge in hand prior to its necessity?

Yes, I agree. Again, because there are so many drive systems out there I would strongly suggest consulting the owners manual. Indeed one car manufacturer may use a different technology (clutch vs viscous drive) for AWD depending on year and the towing instructions may be quite different.

In an emergency or for transportation?

Generally, the transmission issue is secondary for emergency towing. If either axle is raised, both must be. All wheels must turn at the same rate, or not at all.

For transportation towing, check your owners manual.
