Welcome to the Forum...it's a good place for experienced advice and opinions...
QX56...is that an Infinity SUV? If so I'd be skeptical about that towing claim of 9000 lbs. Problem is that when you get into that range you are getting into a tongue weight of over 1000 lbs.
Check the PAYLOAD number for your SUV, not the towing number. Subtract the weight of all your gear, people, dogs, etc and see what is REALLY possible.
Also...never use the 'dry' weight number for any trailer. Almost always that number will jump 600 to 1000+ lbs more when you are loaded and ready to camp.
Good luck with your search and new adventure.
