I've had both, and tow fairly heavy loads from time to time. I don't tow heavy on the freeway or with a 5th wheel, which is where the dually would pay off. On back country roads though, I've pulled 18k with the SRW and been fine as far as stability goes, but I'm not going fast 30mph tops.
As far as the sand goes. Its hard for me to say, because my dually was 2wd. However it seemed to bury the rearend way faster than my srw truck, which will get in fine even without the 4wd engaged. I think that that is because I run a considerably wider tire on my 2500. Fuel milage was very comparable. the dually did a touch better but I'm attributing that to the 2wd.
Hope that helps. Parking sucks, but you just have to watch your fenders and be careful, they aren't that much bigger. If you don't live in a major metropolitan area, you won't have any problem with that.
