Re: 6 Speed or Auto for 2015 JK??
Our 2004 Rubicon has a 5 speed and I've taken it places others haven't gotten an auto to go, so it's certainly not a bad idea off road. However, consensus is that the auto is better offroad these days, so we ordered our 2016 with the auto even though my wife wanted the stick more. I made it her decision and she said she wanted the theoretically more capable vehicle than the more fun every other time you drive it vehicle. Luckly for us we're keeping the 04 and my toy is a 6 speed GTO, so we'll still be able to row our own gears. I guess the point is that you really can't go wrong with either.
