... why did you choose rear bumper over roof rack?

I'm in the same boat at the moment. Can't afford a $2000 swing out, and don't want to put it in a roof rack, so I guess it's rear cargo area unless there is another option.
On the side of my house:behindsofa:
Of course that's for DD, when I'm hoping (lol) that my viair and patch kit might fix the problem if only long enough to the nearest tire shop.
When wheeling the spare gets placed in the back with straps holding it down, not ideal but it will work till I get a CBI rear bumper.
I don't support the roof basket mount, just too many ways for something to go wrong, remember, a life ending fall can happen at only six feet above ground.
There's no need to carry it around for DD purposes
if going wheeling..
You're tellin me you drive around confidently w/out a spare tire? You got AAA?
You must not drive too far from your house / shop / etc?
