I personally have not towed with my Outback (4-cyl), but having towed with other vehicles with similar power/weight ratios, I would say it wouldn't be the fastest, but you would be fine, espescially with a manual tranny. I mean, how fast do you really need to fly up the mountain passes, which only last 20 miles at the most? A little underpower isn't necessarily the worst thing. Just stick it in third and drive 60...
