Rear bumper tire carriers, are they good or bad. I don't really need the space that the spare tire takes up inside the truck, would there be any other good reason to put an outside tire carrier on the truck? I am going to fabricate a new rear bumper and I'm trying to decide if I should do a square tube bumper with tire carrier or a bumper similar to the one Steve is running on his K5 on the pictures from the Powerhouse Roadtrip . At this moment I'm leaning towards the style Steve is running. Pro's / Con's - What do you guys think?
