I have a Chevy Suburban, and did some shopping around recently.
Truck Vault makes a nice system, for a huge price tag - $1000 for a crate!!! Plus they weigh a ton.
Check out this site for drawers:

I then added two nice wire crates on top of the drawer units. They are all light weight enough to take out when I need to haul some stuff w/out the dogs. All of this for a fraction of the cost of most systems.
The other unit I looked at was harder to take in and out since it was heavy, but not too pricey. You may want ot look at them though:

Good luck
