2005-2007 RTs have a FD drain plug but in the 9 o'clock position rather than 6 o'clock starting with 2008 model year. More convenient to service with no need to remove wheel, disconnect drive shaft boot and drop the pumpkin to 6 o'clock for draining. Not a deal-breaker 'cus earlier hexhead RTs are typically serviced in combo with tire replacement.
