The 10K gvwr limit on your 2012 2500 is more for registration and manufactures warranty purposes than actual capabilities. Make sure your registration is right for your actual weight and that your rear tires and wheels can handle the weight and you will be good to go.
Pretty much this. On diesel 3/4 tons you need to watch your tire and axle ratings. And honestly if you bag it or put Timbrens on there's no reason you can't go up to the equivalent SRW 1 ton axle rating as long as the tires are good for it - the components are all the same except for the rear suspension/springs. GVWR on a class 2 truck is maxed at 10k and that can lead to some artificially low payload ratings.
