I have hauled larger 5th wheels and never felt the truck was not up to the task or even struggling. I do find the ratings weird that a SRW mega has more capacity than a DRW. Kind of defies logic.
Maximum trailer tow weight, perhaps since that's just the GCWR minus the curb weight with an allowance for a 150 lb driver. The dually is heavier than the SRW, so if the GCWR is identical, the dually will have a lower maximum trailer tow weight.
With a 5th wheel, however, GCWR typically isn't the limiting factor. It's GVWR (if you follow the manufacturer's guidelines) or rear GAWR (if you don't). Both of these ratings are where the DRW wins over the SRW.
