Here is a link to one I was planning on putting on my SWB. (It's between this and a roof top tent)

I had one on my LWB that was great. Keep in mind, they are a little noisy above 60mph but I've loaded so much crap on a rack like this its not even funny. Very versatile and pretty well made. Be sure to ask for the rain gutter mounts. They technically don't list the raider or Gen I Montero for application so you just find the size you want and the gutter mounts are adjustable so definately no fitment issues. This Tahoe one is 48"X60" and would be full length and width of the Raider's roof. Wilderness also has light mounts for up front, spare tire brackets, high lift et al.. Hope that helps. I'll try to post up a pic of my LWB that has one on it.
