I do about what DG does. I keep a plastic bag with a change of clothes, a first aid kit, matches, etc, in the rig at all times. Also there is an inexpensive fly rod under the seat. My tackle box consists of a cardboard box that contains a couple of inexpensive reels and plastic bags with terminal tackle (leaders, flies, etc). When I get ready to go I usually throw in a better rod and maybe a better reel. If I plan of keeping a few fish to eat I take a wicker creel along.

On my last trip I wanted to keep a bunch of whitefish so I obttained one of those cheap backbacks likre the kids take to school. I think I payed 2 bucks for it at a yard sale. I stuck the fish in the backback and then transfered them to the cooler when I got back to the truck. It was cold enough the fish were OK. Worked like a champ.

Hope this helps.
