I would list it but I may get slapped.
Outback in OBX
I have been traveling to the 4x4 area of the Outer Banks north of Corolla for years. In the past I have made the trip to our beach house 6.5 miles up the beach in a Grand Cherokee and an Avalanche. I recently downsized from the Avalanche to the Outback and I was worried about my beach trip. Well, I made it without any problems. The entrance to the beach is a little tricky, but it gets much worse up the beach if it is high tide and you can't drive on the packed sand down by the water. I saw many vehicles stuck on my trip including Jeep Wranglers, Expeditions, pick-ups, and some other vehicles that should have not been on the beach at all such as a BMW X3 and a CRV. I actually made the trip up and down the beach several times during my stay. I got a little nervous at times, but as long as you keep your momentum through the thick sand, you will not have a problem. I did lower my tire pressures to about 25 psi during the week. Other vehicles in my party were a Suburban, Jeep Cherokee, and an Explorer. At some point during the week, I drove each and did not feel they were any more capable than my Outback. One more note, I had my Outback loaded to the roof (and above using a rooftop cargo carrier) with stuff including my wife, two children, myself and all of our stuff. If you are hesitant to take your Outback on the beach, hopefully my experience will give you some confidence
