They are all somewhat skirting around telling you what you can tow. Perhaps it would be easier for you if we helped you to figure this number out. Take your truck to a
Cat scale and weigh it fully loaded with all passengers, pets and gear you intend to routinely have in it when towing plus a full tank of fuel. Put the front axle on the first scale pad and the rear axle on the second scale pad. Bring a broom handle or something like g as the button you need to push is really high up. When they ask for first weigh or reweigh, it is first weigh (if you use the scales to set up wdh you can reweigh for $1-2/time in the next 24 hrs, 1st weigh is usually $9-12). When they ask for truck number tell them private vehicle. If they still need a number give them your favorite number (they get way too many number 1's).
Now take your yellow weight ticket and look at the numbers on it. Take the total scaled truck weight and subtract it from the trucks gcwr to get your adjusted towing capacity. Take the scaled weight and subtract it from the trucks gvwr to get your available payload. Take the rear axle weight and subtract it from the max RAWR.
The loaded weight of the tt needs to be less than your adjusted towing capacity. Your loaded tongue weight needs to be less than your available payload and axle weight ratings (although a properly adjusted wdh will transfer some weight back to the tt and forward to the front axle). Not knowing how heavy you will load your tt, it is safest to do all calculations using the tt gvwr (the most the tt should weigh when loaded). Ideal loaded tongue weight is 13-15% of loaded tt weight. CalculAte 13-15% of the gvwr for now to get an idea of whAt tongue weight you will be carrying. As others have said, toy haulers have heavier tongue weights but I'm not sure of the ratios there.
The quad bunks or tt with a bunk slide often have an office type area for you to utilize but they come with extra weight and length. Best of luck to you in trailer hunting and your adventures.
