Subaru Forester Towing Capacity: How Much Can It Tow?

I've been researching the Subaru Forester's towing capacity and was wondering if anyone has experience or knowledge about how much weight it can handle. I'm planning to purchase a small trailer for camping trips but want to know what to expect in terms of towing power. What are the max weights, and are there any specific models or years that have higher capacities?
