I was going to get a rear bumper without the spare tire carrier because I don't plan on going to a tire over 33". But I was thinking it would be nice to modify the tire carrier to hold my mountain bikes and/or gas cans and gear basket. That way I still have swing away access to the rear hatch versus using the carriers that use the reciever and block access. Just a thought. I don't even have my Xterra yet, let alone the shrockworks stuff...but the gears have been turning for some time.
