I remember you post. I was planning to do 08 one as well.
Right now I'm limbo since I don't have navigator yet. Let alone second vehicle. Although I've spoken with orgs and they might be able to team me up with somebody. But I need to have 2 people in the car. I've got couple maybes so far only.

I don't think this even requires built rig. Well maybe fast rig aka Baja racer would be helpful although unnecessary but definitely not rock crawler type.
