Lets see....... On the floor area I have:
Milk crate with misc. power tools
-Tool bag with highly used tools
-Tool bag with rarely used tools
-Tool bag with bungee's and rachet straps and such
-Rubbermaid tote with tarp, spare bulbs, tire plug kit, breaker bar, torque wrench and some other odds and ends
-12v impact gun
-10" Sub
-Fire Extinguesher
-Million candle power light
-Jumper box with built in 300w inverter and bag with jumper box cables/charger

On the Lobo Shelf:
-55w auxliary light so I can see all my junk
-700w inverter
-4 recovery straps
-2 shackles
-100+ piece socket set
-2 FRS radio's

Think thats the majority of it. There's a few other odds and ends back there too. I got bored one day at work and weighed everything back there and had over 250lbs. of stuff. All of it is getting ready to come out though. Thinkin about selling the old beast. Gonna be hard as hell fitting all that on the motorcycle I'm driving now.
