Im looking for ideas on a safari bench seat in the back of my truck. I plan to fabricate it myself and would like it to be easily removeable and also be able to rotate it right or left 90 deg for those times the kids and I are on snake/frog patrol along a ditch. Also the usual ergonomic features would be nice, i.e. ladder, gun racks, spot lights, ammo shelves, drink holder etc etc etc. Your ideas are appreciated!

Try to find a place that deals in used school busses or maybe a salvage yard. A Bus seat should work well?

I would like to be able to have 3 adults on the bench at once so the bus seat may be a little small. Good idea though, particularly if I were building it for a jeep. The construction of the bench/accessories is fairly straight forward, its the design of the mount which allows for rotation is what I would like some ideas.

Not a bench, but boat seats three across?
Old rear seat from a full size pickup?
