I have a roof rack for my better half and I to use the RTT on. I may get a trailer later, but they cost a LOT more for what I want. I like the rack more due to the ease of movement and always having it. Also, my JK is not a DD.
As an alternative to the Gobi for those of you with OEM style soft tops that flip back, LOD just came out with a pretty cool sliding rack comparable to the Gobi. Had this been out when I was in the market I would have strongly considered this one.

That's not much of a concern in Wyoming.
To me, the inability to cheaply and easily mount a rack is a major drawback to a JK.
Not sure what "trinket onit" means exactly, but yes, having to spend $500-$1000 plus dollars to purchase a roof rack that allows the removeable top to be utilized immediately after buying a $35,000 vehicle does limit a JK's utility for me. I live in a cold, wet climate and carrying kayaks, boards, and mountain bikes on the roof is much more important to me than taking the top off. I also prefer to not to drill holes into my $35,000 Jeep as a lot of racks require, don't care for excessive wind noise, and don't want my Jeep to look like a jungle gym.
Don't get me wrong. I love JK's and will likely buy one but it's a hell of a lot easier and cheaper to carry crap on steel roofed Jeep.
