We are looking at purchasing a Legend boat (aluminum-either 16' or 18'). The towing weight would be between 2100lbs and 2600lbs. We have a 2014 RX350 AWD with touring package, however it does not have a towing package We have an after market Draw-Tite class III hitch installed. Will our 2014 RX350 tow this boat without any concerns? Thank you for your comments.
