Other than the obvious like a flat tip. I like to keep a clear 4' or so long plastic hose. One small enough to fit in the spark plug hole.
Double the first item . Ditch the other two. If no one comes along before all 48 are gone, you won't care anyway. If someone comes along before all of them are gone, you have items for barter.I like to keep a case of beer, a can of fixyflat, and a good long rope, I get by pretty well!!!
I am going to do the same thing, I've got one in my pickup and was planning on getting another, the ones I like only com in grey but I think you can get a vinyl dye that comes in a can like spray paint, so I can make it blackHey dick I did notice that it also a splash guard if your mudding . But I think im used to my jeep cause im thinking about putting a small console/ armrest with cup holders t the front of it
