It would be interesting for members to post towing scenarios that they have had with the Model X. Frontal area of a trailer and weight will have huge effects, but tandem axles should also effect energy usage. I would be interested in what owners have towed (I know at the moment the only a couple have) and what the results are. Small airstreams, single axle inclosed trailers. Tandem flat decks ect will all have varying results.
