Subaru recommends 8-11% for tongue weight
(2009-13 Forester, yours may be different) compared to trailer weight
. Also, it is 2400 lbs, not 2500. With 200 lbs tongue weight
I don't get sag (putting a lot more in the cargo area of the Forester will do it, though, and I have a 2012, which is a newer model than the 2008. I do not plan to max out the trailer weight compared to tongue weight, but if I did, it would be 8.3%. Keep in mind that once you add the 200 lb tongue weight you have only 1000 lbs of weight-carrying left for the Subaru which has to include all passengers and gear not in the trailer. I don't anticipate carrying more than 500 lbs counting me and the dogs and a little bit of gear.
