Pros and cons of a dually?

[FORDF250HDXLT]

im getting 15+ average with mine with the OD and 3.55's w/225's (384 gearing)
thats with that wind catcher sitting on her back.
front valance/rv cab roof deflector/electric engine fan cooling mods and full synthetic fluid throughout still to go.
and then a turbo latter.
im hoping to see 16 or maybe even 16.5 average mpg someday.

eat your heart out 460 big block lovers.
(what do ya bet id see 7 mpg average with that in my setup.8 if i was lucky?)

Thats great. I can only get 15mpg out of my SRW truck w 3:55 gears

And my 460 will kill your IDI and get 12-13 mpg

for normal day-to-day commuting, shopping, whatever in a dense urban setting, CC duallies require constant attention when driving. I've gotten used to it, I have driven larger on a daily basis. I do like the added security of an extra wheel on each side when hauling a heavy load or towing a trailer. I've recovered enough trucks where a blowout turned into a major disaster. So, under my own rules of build it stout, practice for the worst case scenario, maintaining an exit strategy, and constantly sizing up who to kill first, a duallie fits right in for me

My 89 F350 4x4 7.3 E4OD DRW with a big Reading toolbox body, big wide fire department mirrors, and 4.10 axles turns in a consistent average 15 mpg - a bit less in cold weather or pulling something behind it. I wish it did even better, and it might if I changed axle ratios or went to SRWs, but it's pretty remarkable for what is/ as-is.

The DRW really is not great in snow, though- 4WD becomes necessary more often than most of the other trucks I have owned
