I've had 3 Ram 1500's, a 1997, 2007 quad 4x4, (traded for a Challenger) & now a 2005 1500 ST. I'm looking at a new Ram and saw online where the 2500's have a ton of colors available. What's the pros & cons of buying a 2500 vs. the 1500's. I don't think the 2500 has a 3.55 rear end, which is the best all around rear end for the 2500, don't want to get killed on gas. What do I gain and lose on a 2500?
