Not quite your question but close...I have a 2014 Subaru with the 3.6 - very happy with it. We are buying a 13 foot Scamp and hope to pick it up in July. I had to figure out what type of trailer I could get. The owners manual says the max gross trailer weight
is 3,000 lbs and the max gross tongue weight
is 200 lbs. (the 3,000 lbs requires electric brakes
otherwise the trailer weight limit is 1,000 lbs) Additionally, the cargo capacity guidance on the inside of the drivers side door says "The combined weight of occupants and cargo should not exceed 900 lbs". With all that said I decided that I need to stay under 2,000 lbs. The Scamp 13 would work but the 16 wouldn't.
Two thoughts: First, the 3.6 comes with a traditional 5 speed automatic transmission. That went away with the new models. I do wonder how the CVTs work when towing often. I'm not saying they are bad, I'm ignorant on the topic and do honestly wonder. If Subaru says they are fine for towing then I'm sure they are fine. Second, In my deliberations I picked up an understanding that AWD may not be the best for towing. This is a feeling not a fact and is based on discussions with others. If we keep the Scamp as long as we hope I'll probably look at 4 wheel drive or even 2 wheel drive configuration in a new tow vehicle sometime after 2024. I do like AWD under normal conditions. The good thing is the 13 foot Scamp is small and I'm confident my Outback will be able to drag it around safely.
