Currently I'm running no spare tire and I am in need of having a extra gas on my jeep. Is there anyone out there that has a recommendation for an inexpensive way to mount a gas can, Jerry can, rotopax on my factory tire carrier. I'm trying to do this without spending a lot including buying the gas can

 

Get a tramp stamp and Drill into it and run this

RotopaX Gas Packs- 1,2,3 and 4 Gallon Gasoline

you can mount it sideways and get a extender and you have 8 gallons of gas on the back.
