PackerFan- AS you can see your very valid question brings out quite the discussion among the members of the MOC family as it comes up most every year with the results being very similar. I actually thought I might refrain buuut. The two reasons to buy a dually are for the increased payload capacity and the extra stability, plain and simple. Many argue the stability issue but in simple terms with duals one has an extra set of tires set outside of the singles resulting in a wider stance and as a result there is nothing left to argue. Having towed with both I doubt I will ever tow a rig of this size in the future without one. Now for the drawbacks, they have already been pointed out by the many previous posters and are all valid. One thing for sure I would never own a dually without the 4X4 option as those duals will hang up in snow, mud or soft ground and YOU WILL need to use 4 wheel drive a lot more often to get moving in those conditions.
