Some downsides with a dual wheel single axle...
(1)Flat tires are easier to change on the single wheel set up then the inside dual would be. (2)If ya had a bearing burn up you could possibly, but NOT likely, pull that tire and rim off and run to a safe spot for repairs. NOT with a single axle. (3)Depending on how the chassis is set up you would obviously have HUGE interior fender wells. (4)Depending on your terrain, duals are a very nice place for rocks to get jambed into causing that wild thumping sound and potentially damaging TWO sidewalls, this won't happen with single wheels. (5)The single wheel, dual axle set up is much more convenient to keep an eye on tire condition and pressure, that inside dual easily gets neglected!

I would guess ride would be rough as the axle rating would have to be very high or so to warrant it.

A Load G tire could carry ~3500 pounds which on a single axle, you would need a 7k axle. If you run duals, could carry 14k on the axle or need a 14k axle to match the tires--which is a really, really a stiff suspension-almost as much as a semi trailer.

Granted, you could lower the tire load rating, but why? Might be a lot cheaper to go with two tires with  higher load ratings than 4 tires, rims, etc. with a low load rating.  

The single axle we ran for years, we kept increasing the tire load rating to get a tire that would hold up.

Tandam axles help smooth out road bumps better than dually.  With a dually, when you hit a bump or chuck hole. The tires hit it and the resulting bump is felt.  With Tandam axles,  The front tire my hit the chuckhole, but the trailing tire is still carrying some of the wieght, So only a smaller percentage of the impact is felt through the suspension
