i have a 2016 RX450h with a hitch mounted by Lexus. It is rated for 2000 kg towing load an a 80 kg max. Vertical load on the towball. Way to go is find out the manufacturer of the hitch and acquire the specifications for it. Your caravan dealer should know this too. His numbers on the vertical load are far too high !
