I know that some others have done a few cargo permutations in the rear of the VX. There's always Ldub's cargo/sub box, and I think Kenny has gone through a couple of combinations back there. I think the ultimate cargo area box would be Grandpa Bob's storage box/ bed. If you can do without your rear seat, then I would say go for it. You can always use more storage. Take a look at the threads below for more ideas.
