if a tandem cant turn then you guys need to meet the roll back driver that stopped by the shop today, 4 dual trailer axles, three dual drive axles on the rig and a single drop axle on the rig. uhm, 9 axles possible on the ground for a total of 32 tires. spun it around in the same area every other truck turns around at our shop.

The tandem axles try to go straight, the front wheels have to turn them, the frame flexes left and right especially at the front of the frame as it was not designed for the side loads involved in the tandem axle system.
If a heavy cross member is not added a couple of feet wide to take those stresses, the frame will flex diagionally in addition to the left and right flexing that happens. I have broken a couple of frames from just hanging a tag axle on the back.
Now if you are not loading it, what is the purpose?
For drive, you can use a 3/4 ton military transfer case that has two drive u joints out the back. Some of the older military vehicles had this setup, a carrier bearing mounted on the front axle and the shaft going to the rear axle from the transfer case.
might as well get some tracks like a Bob Cat uses and make a half track, then the rear can be a tag, with no gears.

a 3/4 ton military transfer case is crap at high speeds, and i do have alot of experiance with those, matter of fact its an np200 transfer case, the predecessor of the np205
the banket arguement it wont work comes into play with most things where people arent too familiar with them. i guess the guy who might want a 6x6 truck is as foreign to you as putting an ISB275 in a 3/4 ton truck. then beefing it all up for the gvw you are pulling.
a 6x6 will have a much higher gvw than a dually. the axle is what carries the weight. not tires on the dually.
