Handling comparison: SRW vs DRW at GVW
I don’t think anyone would argue that a DRW is more stable at carrying a TC but let’s hear some thoughts when comparing “apples to apples” For example let’s assume trucks are both new Ram 3500 4x4 di...

Best statement I've heard in a while....Camper doesn't ride on taxes, it rides on the truck.
Comparing apples to apples 100% except srw or dually, spring rates the same, the body roll of the truck body and camper will be identical from the springs up. Width between springs are the same.
The additional tire capacity of the dually(not the moment arm of the wider track rear end) will provide greater stability via less give in the tire(s).
Now of course all the other stuff Kayteg said also will come into play as well in anything other than a controlled experiment where all the parameters are the same.

The wider track of the DRW means the tire sidewalls need not have to support as much weight during a body roll event.
If both trucks are loaded to the GVWR and assuming their springs are sized accordingly, the only difference comes in tire sidewall flex. In theory if you put soft enough tires on the DRW, it could actually experience more roll than a SRW with stiff tires. The reality is you have 2 tires per side plus more width so it would be difficult to make that happen practically.
This all assumes someone hasn't messed up the suspension with something like inboard airbags pumped up too high. I once ended up behind a guy with a similar sized camper to mine but on a DRW. He was all over the place tipping back and forth while I felt barely any movement. He eventually pulled off since he was holding me up. I don't know what the issue was, but his DRW was clearly body rolling far more than our SRW.
