Have had both and there is NO comparison, go with the Dually. If you can, keep your 99 and then you will have a choice for awhile, just in case you don't like the dually. The market for 99-03 7.3 PSD is very good and you will get top dollar for yours, plus it will sell quickly, when you're ready.

I would do it. We own a shortbed 01 7.3 Single wheel and the stability of using the dually would be the deal sealer. My question though is this going to be a daily driver also. How often will you pull your trailer? These questions I would ask myself first before making the deal. Just my two cents worth.
All I can say is that we went from a 2500hd to a 3500hd dual wheel and would never go back to towing our 35'6" 5th wheel with a single rear wheel truck. To me it was like night and day the 3500 dual wheel is so much better and even better if you dont use it for a everyday driver.Good luck
i pull a 39ft 18k gvwr toyhauler. i just went from f250 short bed cc to a f350 cc dually. no comparison. pulls better, brakes better, better ride, more stable. i love my dually. no airbags required.
for that rainy, windy ,twisting road. for when i gotta stop quickly on a curvy mountain road. i have the right truck.
I'll go along with the "do it" crowd, if its possible for you. You're also gaining extra cab room, and the long bed will make a difference in towing also. If you don't jump on it, somebody will.
