Its not like you would be "fast" without all that stuff and that is why the 100 series is great. I remember when I first got mine and my wife asked "If you have a V8, why isn't it faster?"Probably. I'm definitely pushing maximum density with the ARB front bumper/winch, sliders, full undercarriage armor, Slee rear bumper, drawers, roof rack, RTT, awning, and a fridge/freezer.
The damn thing has always been slow. 285 vs. 295 tires is the least of my weight problems. My 2UZ hates me.
