Ok so I've read a bunch about tongue weight being an issue with 1/2 tons and toyhaulers. My 2015 tundra crewmax 4x4 has a payload cap of 1555lbs. So what should I consider my max tongue weight? Assuming I carry next to nothing in the bed and two adults and one child in the cab..question- does passenger weight not get distributed to the front axle as well?
Your payload capacity is not your GRAW....in other words, the payload capacity is in regards to all the "extra" weight being put on the truck, regardless of the location. In the cab, in the bed, on the front bumper....it all applies to the payload capacity.
RAWR is the amount of weight applied directly to the rear axle...typically "most" of the weight on the bed of the truck.
So, add up the people weight (all three) and ANYTHING else you have put on the truck (accessories, tools, ...etc) and subtract that from your door jam posted payload capacity. What's left over is the max tongue weight the trailer can have.
Of course, loading a truck to its maximum ratings is NOT a good idea. Things will break or wear out much sooner than normal. In addition it can create safety issues. Most will only load to 80% of capacity.
