2001 Suburban 2500. I mounted a large Rubbermaid container in the back to keep stuff in. Everything pictured fits in it except the blue water container. I know, its a lot to carry but i dont use the 3rd row seat so i have plenty of room. Up until about 3 and a half years ago i didn't carry much in my vehicles and then after being stranded in the middle of the desert i learned my lesson. The only other thing i did was mount a Serpa holster inside the center console for my G17. Contents of the backpack. I've made a bunch of changes since this picture: I no longer carry the cliff bars, i found they didnt keep well in the Arizona heat! I replaced them with Mainstay bars. I also sold my 2 Condor backpacks and replaced this one with a Maxpedition Vulture II. I have also added a change of clothes for my wife and i plus lots of baby items since having our first child.
