Thinking about taking the plunge and upgrading to Model X. Currently have the Model S 85 I've had for the last three years. One of my main wants is the option to tow. Looking to get jet ski's and tow to the beach for the family and need to be able to tow. I have a 10 year old MB GL 450 that I could get one of those UHual tow hitches put on but I really want to be able to use the X. I've got my eye some of the demo models listed on the Tesla website but the ones I like don't have the tow hitch listed. So are there any options out there yet to tow or coming down the pipeline? Also is it possible the towing option just isn't listed on the website, some are fully optioned out so finding it difficult to believe they wouldn't add the tow hitch?
