Looks cool, but it seems like all their solutions are built around mounting backpacks; there just isn't room in the VX for something like that (IMHO) unless you're planning on permanently removing your backseats. Not to mention you'll need to take out a second mortgage to pay for it. Sample Tahoe pricing list:
Tahoe/GMC MSM Base unit: $1595.00
Optional Drawer Trays: $350.00/pair
Optional Top Shelf: $180.00
