I have a 2012 2.5 with the 6 speed, and also have a 2005 Honda Odyssey. Our popup is about 1600 dry and 2400 max, and I honestly can say that I would not attempt to tow our popup with the 2.5 Subaru. The dry weight of the camper is completly empty, and once you start loading gear I think you would be over the capacity. Again, you situation might be different.
