In the real world how different is the gas mileage between these two? I have a Wrangler now and the fuel costs are about $250 a month and climbing. I want to grab a 2011 but I like the FD2 better because I do go offroad a little. However, I see photos and videos of FD1's doing about the kind of off-roading I'll be doing. Can you get aftermarket skid plates for the FD1? Also what is the "autostick"? Just an automatic? Thanks.
