Pay less attention to the payload and more to the rear axle weight rating (RAWR), especially on a SRW truck.
A TC usually puts most or all of its weight on the rear axle. If the CoG of the camper is behind the axle, it will even transfer weight from the front to the rear, effectively making the front axle lighter.
The tongue weight of the trailer is also carried by the rear axle, amplified by distance.
On a SRW truck, the RAWR is usually limited by the load rating of the rear tires. At some point, no tires with a higher load rating are available.
A DRW truck has twice as many tires in the back, which translates to roughly twice the capacity.
Edit: with a TC and a trailer you tend to be pushing (or exceeding) the capabilities of many trucks. Calculate your weights conservatively. Things tend to be a lot heavier than you anticipate. Wherever possible, get actual weights from a scale.
