Hello and welcome to the Forum, You find a lot of great idea's on this site for your 03' and their are many trails at TSF that you can run on just as you are now. It just depends on your skill level as a driver, it is always safer to go with a buddy just in case you get in a position that an extra rig can help with a strap or a winch. We have a group of Wrangler owners that hold many events at TSF along with other places in SW Washington and NW Oregon and usually there is always someone in the group that is inching to run down there for the day just to wheel but can't find a buddy to run with. You are more than welcome to check out our group at: SW Washington & NW Oregon Group
and attend any of our meetings or events. We are just a group of Wrangler owners that enjoy each others company and enjoy doing things together. If you have any questions, PM myself or n2jeepn and we can tell you more about our group.
