I believe it's a forgone conclusion that a DRW will be more stable than the same (year/make/model) truck in a SRW configuration when carrying the same load. I mean, how could it not be--lol! However, certainly get the impression that a lot of the comparisons being made here are based on overloaded SRW's---some significantly. Comparisons made under these conditions would tend the exaggerate the actual effectiveness of a DRW. I believe if you compared a SRW carrying its maximum rated load vs. a DRW carrying its maximum rated load, the difference in handling would be much less dramatic.
Bottom line, you can make any truck (including a DRW) feel and drive like a wet noodle if you overload it enough.
The difference is the dual wheels that make it more stable with that heavy/tall load in the back..There are a ton of DRW's out there overloaded by manufacturer specs,heck,even an AF 811 overloads a newer DRW but the fact is,overloaded as it may be,the DRW will always drive and handle better for if nothing else,the footprint aka four tires in the rear versus two..
In the old days when trucks were not built Ford tough,some used to put wider tires(12" wide was the standard) on the rear for more stability and a bigger footprint...
I bought my setup for one reason,I needed stability on the side slopes I travel...I certainly don't need a DRW for my Lance 9.6 without a basement but the dual rear wheels makes the slopie roads I travel way more stable.
Both the DRW and the SRW loaded to max and the added tires in the rear of the DRW will always make it a more stable ride.
