the ONLY time a comparable dually is putting more rear braking force into the pavement is once a srw would lose traction, assuming the dually wont.
Of course, there is no SRW that is comparable to a DRW. You can try to cherry pick some spec to make them seem the same.
If you want to play the rotational mass game, go find the actual numbers. The front tires/wheels of typical F350 DRW that are small 17s are much lighter than the typical F350 SRW running stock 35s and 18s or 20s. I think it's likely that there is little difference in the entire rotational mass, but wouldn't be surprised if the 6 DRW stock tires don't weigh less than SRW.
You have to ignore every person who's driven both SRWs and DRWs with the same TC to believe DRW/SRWs are equivalent with the exception of two less wheels and tires. You can do that, but don't kid a kidder.
