Saw a thread that opined that the later the rig (90-95), the greater the chance for rusted rear frame rails. If you live / are buying in a salt-free zone, this might not be a consideration. Have seen a few Pathys in the boneyard up here in the NE with near perfect bodies and rotten frames. My '94 has pretty solid rails, but I've had the undercarriage oiled a time or two in the past. Look for a solid one.
