Fitting two extra rear tires on a pickup does not a dually make – indeed, there is more to the truck than just the extra tires. For one, the rear tires installed on these trucks are larger than your normal pickup tires. Dual tires are usually 16” in size, however these days 18” tires are also becoming popular. Another major modification with these models is their stronger suspension – because they are designed to carry and haul more weight, their rear suspension is much stronger than that of an average pickup. However, this is not true for some models, such as the Ford F-350, which is a dually that uses the same suspension that is installed in the F-250.
These features make a dually truck the best choice for construction and mining companies that need the maximum hauling power that they can get. Private individuals or other companies that require more powerful trucks are also served well by dually trucks. Their extra tires ensure more traction with the surface of the road, which allows for better braking and handling, especially when hauling larger trailers and equipment. The wider wheelbase also adds more stability to the vehicle.

Someone saind to me that if I had duallies I can lose MPG, is that true?
Absolutely. You are adding unsprung, rotational weight. I would expect that you would take a significant hit to your MPG.
Honestly, the entire exercise is pointless as it will add zero fuinctionality to your truck and will most likely degrade it by placing stress on various components. Any "dually appearance" modification to allow you to bolt on extra wheels are hack jobs at best and no additional capability. If you want a dually...buy a dually. To make yours a true dually and do it right would cost far more than it would ever be worth.

So, what are other options that I can hve my vehicle look or be similiar to a dually?

By adding Fender Flares?
Adding fender flares means you can add wider off-road tires if your rims allow it and not get mud and debris thrown onto the hood and sides of the vehicle.
Otherwise they never made a suburban in a dually so IMO it would cheaper and make more sense to buy a Chevy K3500 1-ton 454 BBC or 6.2-6.5 Diesel 4x4 Dually truck to replace your 1/2 ton suburban.
here Is the older body style like your current suburban or go for the newer body style esp when they (GM) brought out the Vortec SBC and BBC Gasser V-8 engines with multiport fuel injection they are quite a step up in performance and reliability over the old TBI V-8 that predated them in GM/Chevy full-size truck and SUVs in the late 80's early 90's
It can be done, yes. But it's going to be an expensive nightmare. You'd be better off by sticking the Suburban body on the frame of a 4x4 Dually truck as a starting point.
The only other thing to do, would be to find somebody to machine 6-bolt dually rears. Then you'll need a body-man to fashion the fender flares.

I might as well just get the other truck such as the dually Silverado or Sierra and just leave my Suburban alone.
