It looks as if the can is resting on the arm and isn't free hanging. I have seen a few carriers on TJ's with 2 cans mounted behind the spare.10 gallons of gas is 80 pounds. That plus a tire is a lot to ask. I don't mind the offset so much but it isn't symmetrical. But that wouldn't stop me on making a decision about it as I'm more for function and if it looks good then thats a bonus.
