from a truck drivers point of view is that i would be concerned about the tongue weight of the trailer. especially since its only a single axle trailer your going to have a lot of weight on the tongue. Next is how badly are you rear shocks going to compress? if they compress a lot you going to have a lot of weight on the rear axle then the front which eliminates a lot of traction for turning. and you may have to drive in 4 wheel in stead of two wheel because of the lack of sufficient weight on the front end. Next is stopping, trailer brakes are great to have and if your going down a hill you have to go slow (with you 4 way flashers on, so everyone else knows you are going slower then the speed limit) and be in a lower gear preferable one low then what you were in climbing the hill. Also a lot of the guys that are talking about towing another Subaru with a Subaru don't have a lot of these things to consider because of the weight displacement of the load. Its just like that Toyota tundra commercial, the weight displacement of that shuttle is just right, so that the tundra doesn't have any weight on the bed of the pickup and its just pulling, if it had and tongue weight or bed weight like from a 5th wheel i honestly think that a lot of parts would've been broken. hope something in that rambling will help you
