Duals on a 6x4 Gator

Those small articulated tractors are so cool! I used to have an 8 wheel Diesel Argo (factory prototype). It was amazing on hills, PLUS it could swim!

6x4 Gators are already "challenged" when it comes to turning, with the front tires trying to get enough purchase to "out traction" the rear to redirect the vehicle path to the direction you want to go. I think with duals, this problem might be exacerbated to the point of not being able to steer much at all. Having said that, I'd love to see you try it cuz that rig would be off the gnarly scale .

Also, when running empty and encountering a small rise, I think you might find the front wheels entirely off the ground quite often with the added static weight back there. I can see you having to run the rear tire pressures very low, and the mid tire pressures almost un-measurable, to prevent this.

My 6x4 M-gator normally pulls the front wheels (look mom, no steering!) just going up the gentle rise entering the garage. Granted, the M model is heavier in the rear than the civilian models, and it's a diesel, so maybe this wouldn't be as big an issue with a stock model.
