I bought a dually because my wife is claustrophobic so I was looking at the largest Arctic Fox I could find and ended up with a 2000 1150, it weighed about 4200#'s loaded and I have stable loads and air bags which I split up because the slide side was heavier and it would ride level with 25#'s on the right and 35#'s on the left.
Now we have a 9000# fiver and while I could step down to a SRW I really like the stability and the heavy duty brakes along with the transmission brakes, can I get that in SWR? Pretty sure but really like the truck and don't see any reason to upgrade the diesel for another couple hundred thousand miles.
Also like having 6 wheels for more traction but that's my 2 cents.
