Almost exactly like Bob. I have 3 50g Rubbermaid totes with wheels. One for cooking stuff, one for tent stuff, and the other for misc. items. Makes loading and unloading a breeze.
I am a disciple of the rubbermaid tote system. If you get the stainless food service grade racks at costco, you can set the racks up to fit the size totes you get. Easy to pack and un pack, just add food, beer, clothes, and kids. But otherwise, I pack and camp pretty light.
For longer things like tents, sleep pads, etc., I have a few large dry bags to throw them in to keep road dust and weather off them.
