Steering isn't really that bad, even without power steering. I had thought of steering brakes but it gets a little complicated. You would have to have 2 outboard brake calipers outside of the belly tub and between the sprockets to brake each side individually. This might be ok if you stick to hard pack trails, but if you get into deep powder or slush those brake will be in the harshest area of the machine, so we were worried about reliability, and not breaking brake lines or freezing up or having willows stuck in there.
Ya you tube only allows 10min movies so I had to cut some off.
Plans for this winter are more body work, paint, interior upholstery on the walls and ceiling, rebuild escape hatch.
