Howdy Kyle,
It seems that the G owners say that the first GW they would start with for tough four wheeling would be the 280G. The 240GD was under powered and I'm not real sure but it may have had some problems. You might post the question in the G,ML,Mog forum. I think you could do a search on it and find some answers. Remember this. Where one machine gets through another might not. What one machine can do another can't. You can find a way to make one look better than the other. And then turn it around and make the other one look good
