I ended up going with the Prinsu Pro, the sale and free shipping played a big part in that decision. I do like Westcotts molle panels better as I don't like how Prinsu's go past the windows. I understand it gives you more room to mount things but think it looks weird.
I don't know all that much either but I bought these to go with the Method 703's I plan on getting when my 4runner comes in.

But thanks for this post, because I checked an I have the wrong size lugs as well so...
I am still waiting for my 4Runner to be delivered but @vready uploaded some pictures of his camping gear set up and gave me the idea to have a thread where people can post all the camping/overlanding gear they have and how it a fits in their 4Runners! Post away!
