I know there are a handful (a small handful, I'm sure) of Roadster owners with a trailer hitch installed. I'd like to get one (to install a bike hauler - not to tow) but I'm a bit confused, and have some questions. 1) The main one I'm seeing is made by Curt (#11322) but, every site...including Curt's...lists it as fitting the 2010 (and ONLY the 2010) Roadster. That's wonderful, except mine is a 2011 2.5. However, the instruction sheet for that specific hitch mount actually spells out the different directions between a 1.5/2.0 and 2.5 installation. So, will this fit on my 2011 2.5? 2) The instructions say that the trailer hitch instructions should be used "...in conjunction with Tesla Motors instructions and Service Bulletins". ...again, just wonderful and great. Where do I get these? which leads to question 3 3) Is this something I can have done by my local garage? Seems like a lot of effort to have my Roadster taken into a Tesla Service Center for installation of this (if they'll even do it - since it's an aftermarket accessory) Do I have to give the local garage any special instructions about putting the car up on a lift or anything?
