I have towed both ways, and of course, the easiest is 4 down. With that been said, it's your decision which way to go. With the trailer, as was said, do you have room to park with it attached at an overnite spot(or unload and remote park), how easy is it to load the vecicle and tie down. Again, weather plays a part in this, hot-cold-wet-dry, etc. Also, age(yours), is a factor. If non of this is a concern, than a trailer is the way to go. Use some kind of protection on the front of the trailer to help rock chips and debris from the vehicle.
