Heres the setup in the back of my 4runner. I feel like its constantly changing but works for me. The main thing is the Sherpa PAK system. The base plate alone is really nice for just securing things. Its just bed lined baltic birch with tnuts on the bottom side for bolting accessories into. Bolts into factory holes in the cargo area as well. Its nice having the peace of mind that none of your stuff is going to take your head off in a rollover or accident.
Not the best picture, but I stack my action packers on the drawer and run a fridge on the left side. Everything either straps to tie-downs on the base plate and the drawer bolts directly into it. Even my power tank straps to the drawers at the front. Nothing moves and all the shit bouncing around doesn't bounce around so its silent which is awesome!
I'll get some more pictures of it while I'm out in Utah next week.
