...the 3.55's which give a trailer max weight of 85-8800 depending on where you read it, if it had 3.92's it goes up to 10-10,500 depending on source...how does that make 1500lb capacity
Because the differential applies more torque to the wheels for the same engine speed and gear with 3.92 than 3.55, about 10% between those two (3.92/3.55). GCWR is what the engine/trans/gears have to move. So let's say the Ram weighs 5500 pounds with 8500 pounds and 10000 pounds of tow rating. That's 14000 and 15500. Hey, that's 10% more again. Keep in mind towing an RV anywhere near 8000 pounds with a half ton is likely to exceed some other rating. The 10k ratings are not exactly helpful, but the extra torque is!
As far as the original question about payload, a correctly adjusted WDH will remove some amount of weight from the TV's axles, thus increasing payload. But it is typically more in the 20% range from those that have scaled weights. Front axle load restoration as well as greatly decreasing rear axle load.
I get that too but imho with the power of todays tow vehicles it isn't a problem pulling it becomes a problem of suspension, controlling and stopping the weight, which the 3.55 &3.92 are the same. Guess that more the point I was thinking about.
