Hey there! Great news about your CRD! Those things have got a load of torque in them great for offroad use to.
The only things I would recommend before you go out are tow hooks on the front and rear and skid plates underneath.....your dealership can set you up with Mopar brand hooks and plates....they work well. I have gone out with people without that equipment and they have been fine, but you never now what's going to show up.
We know a few easy spots to go. Check out
www.kjexpgroup.com we're a local group, based in Milton, and we're mostly into Cross Country tours, expeditions, overland trekking, but we do go offroading for a day here and there for training. We are dedicated to the Liberty, and anyone is welcome to join.
Hope to see you more on here or there!
