Is a dually needed?

[buickanddeere]

Duallys don't sink into the grass and leave ruts. Because they don't have enough traction to make it into wet ground from damp ground.

Yes they do. I've ruts in front of one house in Mississippi because I tried to drive my dually across a wet flat lawn with nothing in the back. Had to put it in 4WD to get out.

they don't have just 'enough' ..... they have more than enough.

more ground patch surface area. less ground pressure.

more traction, less rutting.

almost like magic i know.

I haven't looked at Dodge but both GM and Ford cannot pull eight tons with a gas dually except one regular cab model, and that barely makes it.
Pretty clear, for eight tons, I need a diesel dually to be safe. $65K for a new truck. yikes...
and the interior of the Chevy hasn't even changed for this year, maybe next. Good reason to buy a two or three year old one if findable.

That's why I'm keeping my 2003 F350 dually 7.3 until it dies...
Those trucks are so expensive but mine is still in great shape and should be good for 200K more miles...
By that time I should be ready to push up daises...

Turbys, is a ten year old diesel dually close to today's real world towing capability? Specs today are much better ,but specs sure aren't everything...
another reason for me to find a cherry used one. Drew

Drew...
My truck spec's out @ 250 HP and 535 LB FT of torque stock...
I am running an 80 HP program after I put in gauges, high flow intake, and high flow exhaust...
330 HP and 650 LB FT of torque...
The truck in stock form was plenty but now she is more than enough...
I don't take much credence in those old specs...
My truck is only rated @ 20K total and 12.5K towing with a 11.5K truck rating...
The rear axle rating is stated @ 8.5K but that is very conservative based on the spring packs...
Dana 80 in the rear and Dana 60 in the front gives me 11K in the rear and 5.2K in the front for a total axle rating of 16.2K...
I think that those older trucks were underrated on purpose...
I know several hot shots pulling 26K total all the time...

I've always wondered if running more aggressive tires on the rear wheels in a dually situation would be worth
the noise. Most I see are summer tires. With almost two tons in the bed in a fifth wheel situation with this particular one,
with grippy tires, I'd think it would pull pretty well, particularly with posi or even locked up.
But what about that noise...is it bad for you guys who have done this?

for example
but this could likely do quite well too and I bet a lot quieter:

Just saw an add from an Edmonton ford dealer. New 2013 F350 crew 4X4 dually has for $39,000. They also had about 4 brand new 2012 F550 crew 4X4 diesel cab and chassis for $48,000

thanks Kevin. Local dealers never seem to be desperate...usually those left overs were bulk purchased white trade oriented trucks with not much in them.
now that cab and chassis deal caught my eye, would be pretty cool to make a custom bed just the way I wanted it...
but now that would be serious overkill for eight tons...would never feel anything back there, except for being a lot slower...
But then I'd probably want a ten litre something...Navistar, Cummins, but get the torque up around 1500.:dance1: Assuming the rear would handle it.
