I went through all the old threads and didn't really see anything about what you might keep in your rigs for your rigs. I know in some cars room can limit what you keep. In my truck I always keep things for the truck. In my F-350 I keep: 5 qts. oil 5 qts. tranny fluid 2 qts. gear oil 2 gal. coolant radiator hoses, upper & lower heater hoses belts spark plugs 2 bottles Heat gas treatment extra gas cap extra radiator cap 1 pint brake fluid extra bottle jack role of shop towels waterless hand cleaner portable tool box with: socket set (standard & metric) combo wrenches (standard & metric) screw driver set ball peen and claw hammers punch and chisel set slip joint pliers regular pliers & needle nose pliers adjustable wrenches, 6" & 10" and a few other miscellaneous things plus the usual things like tow strap, jumper cables ect.,ect. I know there's more I need to add to the list. In my Jeep I don't keep much at all, but that is about to change. Has anyone else given this much thought? If so please share as I'm sure my list is not complete and there may be others just starting to supply there vehicle and need some good ideas.
