I love mine and hubby loves his too but is threatening to trade mine in for the 1 ton,
We both have the 3/4 ton, you have to get XM radio it is great, they tow wonderful and get great milage, I get 18 on the road and 12 fully loaded, over long hauls (ex 1600 mile trips)
They are firm in suspension, I have the 4 door, hubby the extended cab, his is like a sports car compared to mine, mine more like a caddy, both are 4-wheel drive
They did have a sensor recalled, and they had trouble with the injectors with the first couple years, but I think they got that all sorted out, just have 53000 on mine it will be 2 in October, and the initial troublew with injectors did not happen till they hit 110000, so if you trade in to take advantage of the tax stuff, then it is not a big issue, I am not sure I will have mine till it gets that old though, must highly reccomend the pop up bed hitch, great for being able to load the bed fully with out the hitch in the way, very easy to use, also sray in bed liner a must, just to protect your investment
