I'm thinking about having my wife's family steel fabrication shop work up a custom rear bumper - but 1 thing I notice is that most of you with custom rear bumpers with tire carriers have the spare tire on the right hand side. Why is this? Wouldn't it be less of a visual obstruction in the rear window if it was behind you on the drivers side?

I know when I pile boxes into the rear of the 4Runner I stack them higher behind me than in the passenger side of the cargo area - I feel like I'm not losing as much visually as when I have them piled higher or blocking more of the passenger side of the rear window.

Am I missing something as to why it shouldn't be on the Drivers side? The only thing I can guess is a weight issue with the gas tank also being on the driverside.
