I dont want to go off on a rant and possibly get myself into trouble. But If you view alot of the rack companies, they are all the same sizes. mount or no mount its the same size cages, all you gotta do is make your own mount. it's easier for me to say that because i dont have a slanted roof like the X does. But then again, if you have a rack, id rather have your option because you dont have to drill even more holes in your roof. our roof's cant handle that much anyways. so i guess it would be a good thing if you already have racks. (does that make sense) I think i confused myself haha.
about the late night posts. I work night shift in costa mesa as a radio dispatcher. So im workin 8pm to 6am down here in SoCal. I hope this rack finds you, sure looks like a good product.
