I have basically the same vehicle, a 2016 Sunseeker 3010DS and tow a 2007 Honda CRV with absolutely no problems. It weighs about 3400 lbs. Another friend has a 2016 Leprechaun similar size that pulls a 2014 Honda CRV, which is a four wheel drive and is a little heavier - again he has no problems. Unfortunately, CRVs from 2015 on are no longer flat-towable. My friend found a nice 2014 because of that. Your Forester and my Sunseeker are both rated for 7500 lb pulling although I'm not sure I'd want to go that high. I pulled my toad to Alaska and back with no problems last summer.
