Rangersedge,
The 6x6's are very maneuverable. The turning radius on the 6x6 is a about 42" larger (186" versus 148"), but I have not noticed problems getting around in the woods.
It's a trade off...larger turning radius, but much more stability and traction.
Remember, though, all 4 wheels are turning at the same rate (always locked), so you can burn through some tires and tear up some turf quick if you're making a bunch of turns.
Of course, you might take everything I say about the 6x6 with a grain of salt...I'm really sold on the machine. We started out using ATV's in our business but they were too undersized and unstable around ponds. Then we used Kawasaki Mules for awhile, but they did not have the power to pull the airboat out of the lakes. So we landed on the 6x6 and haven't looked back. It performs well on steep slopes (front to back AND side to side). It's geared to pull HEAVY loads. It has been in some really muddy, nasty places and never (knock on wood) gotten stuck.
Is a 6x6 the right machine for everyone? Probably not. Is it the right machine for us? Absolutely.
