TT Weight limits: theory and reality

Let me ask the same question another way. "If" the tow vehicle brakes don't matter and "If" the trailer stops itself, why has my stopping distance increased with every one of a dozen tow vehicle/trailer/brake controller setups that I have towed with in the last twenty years?---

If your question is addressed to me, my answer is -- did someone actually make those statements? If so, you need to address your question to that person.

---Shouldn't the tow vehicle stop in the same distance as unhitched?---

That would be very unlikely. It would require the TT's braking characteristics to be identical to the TV's braking characteristics. Some people claim their TV/TT can stop in less distance than unhitched -- some people claim the opposite.

---I contend that tow vehicle brakes do matter and I think that those designed to stop 9,000 pounds will work better than those designed to stop 7,000 pounds.---

You're the only one who's wanting to compare vehicles with brakes of different capability.
As I stated in a previous post -- the issue which led to this line of discussion was -- for a given TV with a given GVW, does a greater amount of unused payload capacity give shorter stopping distance.

---Can you tell me that "some" of the trailer weight does not tend to shove the tow vehicle down the road during an emergency stop?

That would depend on how the trailer brakes were working.
If you're talking about the trailer brakes not working -- I also addressed that in a previous post by giving an example of a 7000# GVW TV stopping a 14000# GVW combination with no trailer brakes.
