4 down towing vs trailer

We tow our vehicles with both a trailer and 4-down as well. To deal with the trailer, it is nice to only trailer a vehicle that can also move the trailer. That makes putting the trailer in a storage area, or negotiating smaller rv parks much easier. I prefer the trailer over towing 4-down, because there is less wear and tear on the vehicle, I can back up, and there is room for other stuff. It is easier and simpler to tow 4-down, but some of our vehicles are not 4-down capable.
