Got a chance to try out the 100 this weekend
Ran 4 trails near Ouray; Yankee, Governors Basin, Black Bear and Imogene
The vehicle performed well and you can feel when the ATRAC kicks on. Tires probably would have slipped a bit on the 80 too, just wouldn't have noticed.
My daughter (also an 80 owner) shared driving with me and described the handling this way "It handles like a fat 80"
She liked the way it handled, she was just getting use to the slightly wider tire placement. She also described the ATRAC kicking in as the fat 80 waddling
This wasn't a ding on her part, she enjoyed driving it and thought it did fine.
I really didn't notice the difference from Solid Front axle to IFS, but then we didn't go over any big rock obstacles.
I really liked the 5 speed in low gear while wheeling. When I put 4.88's in my 80 I could go down hill in 1st without having to ride my brake like others. Stock gears and lo with the 5 speed was the same. The other trucks were riding their brakes while I just let the gears take me down.
Overall, I was very pleased. It did handle slightly different with the ATRAC, nice feature but a little strange the first time you use it.
It also did a great job pulling my Kimberley Kamper to Ouray and back
