Question from a newbee. 2500 vs 3500 I can get by with the payload and towing of a 2500 (barely) But I would perfer the 3500. Now the problem is I live at 9,000 ft in Colorado and the snow and ice concerns me with the duals! Has anyone tried both in harsh steep gravel hills? And no I cannot afford a 2003 3500 with the single rear. I'm looking at 1999 and 2000. Thanks for any advice. Glenn
