I'm in the market for my first trailer and considering the TAB 320 S or 400. I currently have a 2009 Toyota Highlander Hybrid (stock) which I would like to use as my tow vehicle. I believe towing the 320 S would work with the Highlander, but I'm unsure if it will appropriately pull the 400 based on tongue weight and GVWR etc. I would appreciate feedback from this Forum to help me understand the numbers, considerations, basics about towing, and if the Highlander will pull the 400. Thx!
