I'm not talking about gas and oil but what do you keep in the bed, tool box, cab, and what ever. What do you keep on your mower?
In my dads gmc envoy he has-
trailer hitch and all sorts of balls
12v air compressor
various hand tools
and a 9mm.
On my mower I just keep my leatherman with 42 piece bit set.(that is on me most of the time)
