Granted I'm just a GT, I have a class II hitch on mine and have used it to pull a ~800 lb. waverunner along with 100+lbs of crap in the car with my 200+ lb. friend on a 6 hour trip before with no probs. Also have towed 12 ft. trailer with alot of stuff in it. But your trailer alone is 900 lbs. I've seen a bonneville pulling an 18' boat before, whatever thats worth.
The biggest issue you have is to not get into boost while towing. I would just be careful and not beat on your car while towing, and stay in the right lane, lol. I've also heard the you can just pop off the supercharger belt, but not to sure on that?
