ahhhh the 3000 dollar question. In general driving it feels fine. I have not towed with it yet. It has a 6-speed transmission and of course diesels are torquy. Still going up a small incline in low range it bogged down and it wouldn't spin the tires in loose sand. IN LOW RANGE. I am thinking it needs to be re-geared.
Quick feedback is that it's critical to get the torque right on the track bar. Also the tires give a much better ride on the washboards.
are you still loving the supersingle upgrade? i just did 600 miles in the dirt with little issues on the toyo's but the soft sand is still a concern, all that weight and those little front tires want to dig in.
