You know the rack thing is dependant on where your primary off roading/ exploring is. Back East here in New England I am not a big lover of the rack, I had it on and off my truck several times, for the most part they are a hinderance on the tightly wooded and overgrown areas we tend to explore around here. I cannot count how many times I've seen lights ripped off by overhanging limbs, or at least have it be a a constant issue on a trail ride to stop and hold branches up or fold down the lights so they dont get hit. When you are out west or in a more open area I can totaly see having the rack and lights.
The other downside I see to roof-racks is the un-bearable urge most rack owners have to load the things with 300 + pounds of fuel and gear making the truck precariously top heavy. I went through it myself and finally got to the point the rack held little more than some bulky lightweight gear and my chain-saw.
I personally like the look of the disco rackless.
Just my .02 on the matter.
