...because they're tough to admit having to ask, but the answers here are too good to pass up:
1.) What's an uninterruptible engine?
2.) Besides the roof, where else than under the 4Runner ('99 Limited) can I store the spare tire?
I am considering putting the tire into the vehicle, where I would actually be able to get hold of it. (I'm kinda old.No, I AM old.)
3.) Does 4WD also work when backing up? Is there a limit on how far you can back up?
Well, those are enough dumb ones. Any advice is welcome, except "go read the manual" I have the manual and have read it twice....
