I'm a new RT-S owner and was told to get a battery tender. I was also told that you can hook it into the 12-v lighter in the truck with the right adapter. I need some help. If that is true can someone tell me what adapter I would need to hook my battery tender up? Also, where can I get it from? Hit the interstate today for the first time. Rode about 20 miles. :yes:Thanks, Blue RT-S
