New to the jeep world but very excited about my new 2013 Sport Unlimited S package. I placed my order on Saturday with the following specs: black, supplemental air bags, connectivity, premium sunrider soft top, 6 speed manual, with 3.73 rear axle ratio. I orginally put down 3.21 but after much research here I called this morning and had him change it to 3.73. I was in full panic mode last night over this. He said its still OK to make changes. My plan is to do 90% road driving with a 50-50 highway to city travel ratio. No immediate plans for bigger tires, lifts or towing but I wanted to keep my options open. Dealer sold me on better MPG with the 3.21 but I think I would rather have some more power with the 3.73 just in case. Or for resale. From the research I did on this board it doesnt seem to be much difference between 3.21 and 3.73 in regards to MPG. Now I get to sit here and wait 4-6 weeks for delivery. Also, planning on ordering some running boards since I didn't want the stock ones. Having fun with my new hobby. Thanks to all the posters here who really help out the rookies.
