Okay based on your reply I would definitely be buying a 2 door, better for trails and it does sound like you need the extra room. Next is the top, depending on where you live, but if your in an area where you have a lot of cold days like me, then you might need the hard top, but if your down south, then I would opt for the soft top. Sounds like you don't need to worry about security of the top, if you are riding with a Rottweiler. Are you wanting new, slightly used or older? I personally would avoid the 4.0L and the 3.8L. If you are looking for new or a 2012, then you can get into a better engine, the 3.6L, or if your looking for older, a lot of people like the earlier 4 cylinder engines. If you have access to cheap parts and can DIY then I would buy the base 4x4 and build it up as you can afford it.
