Regardless of wether or not you go on any trails (which as others have stated, you can in a stock VX), you should go. Not only is Moab extremely beautiful and picturesque, which is a good time in itself, you will have an absolute blast being there with all the other VXers and Zus. And, if you plan, you can go on the cheap and camp at The Portal with other Zu freaks so really you would just be paying for gas, food, and nominal camping fees!
DO IT.
