Very nice looking rig! Congrats!
Some other things you may also want to look into are the Break Controller and tow mirrors.
For the break controller I recommend a Prodigy P2 or Prodigy P3. These are very good controllers. For the Tow Mirrors I recommend the JR Products Grand Aero or Aero 2. These are some of the best clamp on tow mirrors. There are some cheap Tow N' See mirrors that use suction cups to stick to the mirror glass on the side view mirrors. They work okay but they are not the best. I use them now but will be picking up some Aero 2's soon.
Thanks!
