We'll skip the questions about "Why"...

The answer to your question is going to depend entirely upon what parts you can find at a U-Pull-It Salvage Yard. You might find all the parts you need, there, for well under $500. Or you might have to hit up eBay, etc.

Without knowing the particulars, I can't say for sure, but you might run into problems connecting suspension and/or your drive-shaft.

I guess the real question is, just how badly do you want this to happen?

I would say it would probably be cheaper and easier to just sell it and buy a dually.

If you have to ask, and cant do the work your self, its more then you can afford

Well, I want it badly to happen but I am patient at the same time.

I want to know how much the parts will be and the labor cost.

But it's been my dream to have a dually Suburban similar to the one in Twister.

Besides, think about it, an SUV that cam seat 8-9 people with a power of aee truck.

The "mod" Doesn't change the GVWR of the suburban.

Um, ok.

If you're starting with a 3/4 chassis, the axle swap should be straight forward. I'm assuming it is a 4 wheel drive, if so look for a match set at a junk yard, look for something off of a Chevrolet or GMC from 73 to 91. If none are available, bring a tape measure and start looking. Otherwise it is cutting, welding, and bfh to make it all fit. The more you use bfh, welder, and cutting the more expensive and time consuming it becomes.

As far as costs, it depends on how much parts run. If you shop around, go to swap meets, or peruse craigslist, you might score a bargain. Fenders, LMC, the dully fenders were usually fiberglass.
Practical side of me asks "why?" The truck guy in me deep down inside admits "that might be somewhat cool, maybe." It won't change the capacities or ability, and now instead of four tires you now have six to replace. It keeps getting more expensive.

Maybe were all over thinking this?

He couldn't just get some adapters and add he wheels ?

For those of you that want the dually look on a truck you already own, then consider a dually wheel conversion kit manufactured by Arrowcraft. Depending on the truck, most Arrowcraft Dually Conversion Kits will run you about $2000.00. Arrowcraft dually body conversion kits or dually kits consist of 2 rear dually fenders, rear adapters, front wheel adapters, 4 Alcoa Aluminum Rims, and 2 steels rims, caps and lugs. However, you could save money by shopping around for the adapters, Alcoa custom wheels and steel dually rims. Other cost involved would be the dually tires, paint and the cost to extend the gas filler neck. http://www.customduallytruckaccessories.com/dually-wheel-conversion.html
