Bill,
The Highlander Hybrid has a GVRW of 6150 (I just looked it up on the Highlander spec sheet). I have been all over the web looking for a GCWR for this vehicle and have only found it listed here:
http://auto.howstuffworks.com/auto-p...cle/gcwr37.htm 2009 GCWR = 8158#. Does not list for 2011 and I can not figure out where the numbers came from.
The difference is now 3396# total capacity for passengers, cargo and trailer.
Like you, I did not want to get involved in the Toyota magic load calculations. I am still waiting for a real world, documented proof that in the Toyota world there is no relation between Curb weight, GVWR and GCWR.
