GM is running on an aging design and won't have the new body style until 2015 models. Ford must be due for redesign in the next couple of years. Ram is very new and has probably the nicest and Roomiest interior on the market today. They also have the highest towing ratings out there for 3500 dually But any of them will be a decent towing platform. I suggest you go out, drive all of them hopefully all on the same day and over similar roads. Then using that information, pick the one you like the best and can get the best price on.
