K2500 suburban towing 2013 Sprinter 311 BHS

[summerhummer]

Hi,
Similar to the other post I too am looking at the 311 BHS Sprinter I ran through the numbers. I know I am the ultimate decision maker but I would like a review.
TV is 2006 Suburban 4X4 with 8.1L and 4:10 rear.
GVWR of TV =8600... Curb weight 5910 leaves a payload of 2690

TT dry weight 8260 max Cargo capacity 2735
If I use 13.5% of max load as estimated hitch weight I get 1484 on the hitch.

I think this makes my payload =8600-5910-1484-650( passengers)-300 (gear includes hitch weight )=156 left in payload Not very much but I don't have 650 in passengers its probably 550 but allowing room for growth of the young ones over the next 5 years.

I am estimating my loaded weight to be around 9760 This is carrying 1500 in cargo in the TT . The vehicle is rated for a max of 12K Additionally I am a weekend camper so I don't envision 1500 in cargo. Fresh water is from the camp site most times. Is this crazy will it burn out my transmission? I would like to know how others on the board with the same set up feel about the experience . I have Pmed a few but no responses. I am looking at the blue ox sway pro or equilizer hitch. Use is South east mainly Ga, SC TN FL. I would love to go west but I am still working so I don't see how that is possible. Please let me know.
