While I won't pretend to be an expert on cars, it looks like we're around the same age, so we probably have a similar amount of driving experience. Personally, if I had the purchasing power to afford such a large vehicle, I would go with the Ford simply because it's not a commercial vehicle and can be driven with an entry level license. What exactly do you need to haul? There are so many smaller cars that have alot of towing capacity. The newer Subaru Outbacks have a towing capacity of almost 3000 pounds. Even a Toyota 4Runner can get you up to 7,300 pounds. My family has a similar vehicle to the the Excursion, the Toyota Sequoia, which is nice to drive at highway speeds but a bit of pain to park. Unless you legitimately need such a large amount of towing capacity, go small. You'll save money on gas and a good amount on maintenance.
Whatever vehicle you get, be sure to look into safety reports/features as well. You just never know when you'll be in an accident, and you want to be safe. You can be the safest driver in the world but you are still interacting with other vehicles that can, and will, make mistakes.
