First, is it jerry or gerry? Anyway, Im looking for some options to carry maybe two 5g jerry cans full of gas. Difficulty: stock bumpers. I was thinking about one of those trays that attach to the trailer hitch but that may stick out too far off the back, but that would kill my departure angle. Is there anything available to mount behind the spare tire? 10 gal of gas should be around 60 lbs. Would that be too much extra weight on the tailgate? It would just be there on transit and when the destination is reached, we would refuel and remove the cans.
