Changing to duals shouldn't be hard at all. All you would need to do is get a bumper with the cut outs off a 1500 and then a dual exhaust system. Either stock or aftermarket, whatever you choose. Another option would be to put a dual system on your truck with your stock bumper. That's what I did on mine. Personally I like the look a little better and wanted it to be different than every other 1500 with an exhaust system on it.
