For me at least, In the past I owned a F350 dually.. And swore never a dually again. Current truck is a SRW F350 Long bed crew cab, and Love it.
parking in parking lots is easier. Yes allot of truck hangs out but it fits within the lines. no need to park way out there.
fast food drive thru was a mission with rear fenders...
bank ATMs are easier...
Some parking entrances with swing up gates are tight. And a dually fenders would hit.
if the SRW will perform task on hand I suggest SRW over Dually, but if you need the extra capacity then you have no choice.
