That's a good idea, but Aluminess will also make the rear mount for a box, which you can use with your step bumper as stated above. There aren't a lot of them, but I've talked to them and they will do it. You could do right or left since it is a custom/occasional build for them. The only stipulation is weight. That carrier is designed to only hold something like 50 lbs. which is why they mainly just market it for the spare. I personally think it would hold much more just fine, but that's what they're going to tell you when you ask. Good luck!
Here's what I did:
As you can see in the last pic I have an Aluminess spare mount (not mounted to my bumper, it is not Aluminess) and a door mounted box on the right. It probably has about 100 lbs. sitting on it with generator, 5 gal of water and 25 of fuel.
