Don't worry about your rig. It might even be best to ride along on a trail ride so you can get an idea of what seems to work and what doesn't. This club is very great about helping out. Just read the post from Ed (Moossin88) about breaking an axle shaft on the trail the first night of the Mohawk trip.
If you have any questions like what tire do guys recommend, lift kits, SYE, anything Jeep related, we can offer you real world advice. If you read other forums guys always post stuff like "what lift should I get" and a lot of times the guys responding had the lift installed by some shop and have never taken their rig on more then a dirt road. The advice you will get from JT4x4 members is what seems to work on New England trails, which are different then other places. If you look at the pics you will see a lot of the trails are tight, there is a lot of rock, ledges, a little mud, some water crossings and a LOT OF FUN. The biggest issue when building a Jeep is the $$$. Look around on places like craigslist, and when places like 4wd Hardware runs sales and you can build your Jeep with out having to take out a second mortgage.
Post up any questions you have and someone will help you out. If you do this long enough you'll return the favor some day.
