It's my understanding (which is always in question) that with a proper WD setup, hitch reinforcement, etc, payload will not be an overly limiting factor. It was recently explained to me how manufacturers payload ratings do not account for any trailer weigh being applied to front axles. With that factored in, assuming we carry most all gear in camper, likely behind TT axles, it seems we are in good shape regarding payload.
Don't be too sure about that. SUVs typically have a low payload rating in comparison to a similarly equipped PU truck in the same drive train family. Not always, but often. This is due to the extra weight of the vehicle's mass, and the softer suspension used to give the SUV a cushier ride.

2) The 790 lb tongue weight you cite, is 13% of dry weight of 5800 lbs. As you add "stuff" to your trailer, you need to put "stuff" in to increase tongue weight to maintain the 10-15%. Assuming your loaded weight of the trailer will be 6300-6500lbs, might be light. You will be surprised how much weight adds up quickly. But, lets assume 6500 lbs, that means your tongue weight should be 845lbs (assuming you maintain the 13% ratio). The WD hitch itself, you should estimate around 100 lbs. So, 945 lbs there at the tongue, although some will obviously be distributed forward and back. You are setting yourself up for a problem if you put all your stuff you add to the trailer in the back of the camper, behind the trailer axles. So, you need to make sure your cargo capacity accommodates your family weight, to include the kids and the dog, the 945 lbs, and anything else you toss in the vehicle. Don't think cargo capacity doesn't matter because the WD hitch puts some weight on the front wheels. Cargo capacity (aka payload)is the capacity of the whole vehicle.
3) While it is true, the WD hitch puts some weight on the front axles, you have to be aware of how much it moves forward, because you could easily get to max, or over your GAWR (Gross Axle Weight Rating) for the front axle. Another limiting factor.
4) As has been pointed out numerous times, one typically exceeds cargo capacity before you reach max trailer capacity. It's a physical fact, and not something that should be ignored.
These are 3 excellent points that need to be given serious consideration.
I personally have towed 2 different rigs close to my tow vehicles rated capacities (note the plural). It can be done safely, but there will be limitations. I can also tell you that there is a marked difference between being close and having plenty of margin.
If you don't need the 3rd row seating, a similarly equipped PU will have a higher payload, and a higher tow rating. Generally you can get far more truck for the same or less money than a large SUV. I have mostly owned large SUVs, including 3 Suburbans. My Sierra is my first PU and I keep asking myself why I waited so long.
I wish you the best! When all is said and done it's all about the fun!
