Hopefully this is not old news. But I found on the used 2008 RT I picked up last year, if you look back under the luggage rack at the rear socket, the opposite side is set up for a socket as well. Even the bodywork has a molded in recess for the additional socket. I plan on ordering 3 sockets from Powerlet and running all of them to a Blue Seal power panel. Will make it easier to hook up the Battery Tender during the winter.
