Hello, Im a new member, just signed up actually, and Im wondering if anyone can answer a quick question?. Im currently looking at my first purchase of a tesla model S. Im looking at a 2014 85kwh model S from Telsa CPO program. I called tesla directly for an answer who referred me to the regional representative to email. I did email the representative and havent recieved a response so thought I would post. My question pertains the addition of a second or dual charger into a model S. I see I can purchase one on Tesla's site, its shipped to my local service center and installed. My question is can any model S have a dual charger installed? Does the S need to be a certain model, year or have certain options in order to have the dual charger installed? I appreciate the information. I realize the dual charger is not always needed but I drive on average 40k miles per year or 150-150 miles per day. Im thinking the additional charger would come in handy on the road at charging stations that are not superchargers. Thanks in advance.
