You should be able to move the mounts on the Load Warrior around a bit even though it doesn't look like it. You can put the mounts between any of the smaller tubes of the Load Warrior. The mounts on the Load Warrior don't exactly match up with the cross bars on the VX, but you can get them pretty close. I actually took my Load Warrior apart and cut a little bit out of the middle of it so that it fit the VX roof rack perfectly.
"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair."
