I'm getting some mixed advice about towing with a Forester. We are considering buying a small popup camper, and also maybe a small utility trailer. The camper would be for there-and-back trips, not road trips. The utility trailer would be for very occasional moving of furniture, lumber or garden type stuff. We would try to stay well below the prescribed towing capacity of 2,400 lbs., and hopefully get trailers with brakes. We would also install a transmission cooler.
The main comment against is that it would be hard on the transmission over time. We got that from both a mechanic we really respect, and an RV sales person who we don't know at all. Online BBs have tons of discussions of people saying they do it with no problem.
The car is a very base package, but has the standard 2.5 L 4 Cylinder engine.
