The 2 biggest advantages to having duals....

1. Added payload with additional tires.

2. There is never sway or fishtailing in the rear, like there can and will be with single wheel trucks, especially with a bumper pull trailer that is loaded heavy at the front or rear....even a trailer house delivered 350 miles down the interstate. I've had the rear of single wheel trucks whipping pretty good a few times. It's not a good feeling.



I scrap a little of everything but mostly cars and big iron, so I cross the scale @ over 30k# on a regular basis, so I like my duals. If the job is too big for my 6 cyl F150, then it's big enough for the big pickup.......but like others have said, if the jobs you are asking the truck to do are mostly smaller, then a single wheel truck should do fine.

If I lived closer to my pick up & delivery points, I'd probably settle for a smaller trailer and pickup. The down side to a dually....as most of us know, 10 ply tires are not cheap and every time it's in motion, 6 of them are wearing out instead of 4.
