How do you get into this "double extended mode" My dealer mentioned something about it being able to get another 2 inches in rock crawl mode but I can't figure it out... "why do I need it?" I live 3/4ths of a mile off road and there is no going in or out without 4 wheel drive... up a 23% grade at that. there is a short cut out of my "development" (haha) but that is a 35-40% up hill grade and the clearance would help the breakover point to get to the normal road... (this would save me 15 minutes) so I'm veryinterested in raising the susp... I'm also getting an ARB Bullbarwith a wireless 10k lb winch built in... has anyone else added this yet?
