I don't think your giving a DRW it's due. The two extra tires are not for nothing, it equates to stability, that's why they sell them and why guys that have big trailers use them. I pull a 38' Fuzion with a DRW and never has it felt unstable or pushed around due to wind and Idaho is every bit as windy as North Dakota (I used to live near Jamestown).
If you don't want a dually and would prefer to downsize, I get that. However a DRW will change your towing experience 180 degrees with your existing trailer.
