Keep in mind the people that are saying a 1/2-ton will pull it are just concerned with that... pulling it. If your telling us your going to load up your suburban with kids, adults, gear etc + tounge weight of the camper you will be in 3/4-ton territory.
My 3/4-ton has a max tow rating of 9900lbs with a payload a bit north of 3100lbs. You may have a half ton rated to pull 9,000lbs but a payload of 1000-1400.
The situation would be different if you were talking about yourself and your wife in an extended cab pickup. Then you would be pretty good on payload. But I know first hand from my brother-in-law with my nieces that even with his 28' camper he loads up bikes, toys, firewood, dog kennels, etc etc and if he were using a 1/2-ton it would be long over payload. Even with his 3/4-ton he is debating on air bags due to squat.
