[Gwenne & Len]

We have not put a WDH on our Highlander because the factory did not recommend it, as it is a 'unibody' with no frame.......ours is a 2012, don't know if it has changed. We also put most of our weight over the axle in the TM, as we are on the edge for our tongue weight, but we never have sway. We are careful not to have much weight in the back of the TM. My 2 cents....
