I wouldn't take a Forester
I wouldn't take a Forester through any challenging off-roading. Turbo or not, it doesn't have the articulation or gearing for it. My best rock crawler/mudder was a 120HP 4 cylinder Wrangler with 35'' tires, it's all about gearing and articulation.
I have towed my camper up a trail before. 1st gear in my 6m is low enough that it didn't even struggle. But if I want to do serious towing or off-roading, I have a 4x4 F-350 and a 4x4 Jeep with lockers
