This is a pic of my rig:
Plastic sled with low sides - I bolted/washered a Rubbermaid container to the deck of the sled (I sandwiched a piece of 1/2 in plywood between the bottom of the box and the sled to make it rigid and give the bolts something to grasp.
The two eye hooks in the end of the Rubbermaid box are for attaching a bungie, which holds my bucket seat in place. Inside my bucket seat is a smaller bucket which carries my most used gear.
Inside the box is a life vest, throw rope, extra bungies, and extra tipups.
There is plenty of room for other stuff - including a small stove.
The auger stays in place attached with a singlebungie cord.
I have no shelter or gas auger. I take the minimalist approach.
The best thing about my setup is that it slides right into the back door of my Blazer - when seats are folded down, and fits perfectly between the two rear doors - no need to shuffle all my other gear inthe back of the truck.
