Explain how your pickup knows that you have unused CCC capacity and benefits from it? I say that if it is overloaded by 300 pounds, then it is overloaded by 300 pounds and has no idea why.
Toyota says that, properly loaded, my truck can safely tow a 10,300 lbs trailer. The brakes don't care if that is a 5th wheel, flat deck of bricks, etc. Therefore they believe that the Tundra's brakes plus the brakes of the 10,300 lbs trailer are sufficient enough to safely bring my vehicle to a halt. Furthermore, they met federal standards to make that claim.
My next trailer will be 6500 lbs dry with a max wet weight of 9500 lbs. I know that my total dry weight will be around 7000 lbs with options, possibly another 500 to 700 lbs of gear for a long trip. That means that my trailer manufacturer says that braking system on the trailer can safely stop 9500 lbs.
Since my trailer will usually be at around 7500 lbs, my trailer brakes will have 2000 lbs in reserve braking capacity.
The SAFETY ASPECT gets thrown around so often on this forum. They say the half tons can pull the weight, but can they STOP the weight? Well, my rig will be rated to stop a full ton MORE than I will be carrying (we aren't even going to get into the fact that the Tundra is rated to tow up to either 3500 or 5000 lbs without requiring brakes. That would further add to my point, but I am not even going to add that argument).
So, how do my brakes (SAFETY... right?) know if that additional 300 lbs is in the trailer or the bed of the truck? The brakes neither know nor do they care. I am still 1700 lbs below my brake rating.
Now, everyone agrees that a heavier tow vehicle is safer. By adding 300 additional pounds to the tow vehicle weight, that makes the truck that much less susceptible to sway and being "wagged by the tail", right? Again... SAFETY.
Understand my argument now?
