Jacks....bumper, floor, scissor on Driver

A bumper jack isn't rocket science. You could take it out and practice, but you didn't say what car/jack you have. Some later models have a large hook and or a tang that goes in a slot through the bumper. The jack in my 67 fish hardly has a hook at all. I wouldn't dare to use that thing.
I once helped a lady change a flat in a store parking lot using the jack in her Pontiac. I thought, "This is a pretty neat jack design". I got one from a parts yard and tied it onto my OEM jack with a bungie cord. After 14 years I've never needed to use it. 1978-88 A-G BODY SCISSOR JACK OEM GM T TYPE Car Jack Buick Chevrolet Pontiac | eBay
Do have one flat story. A few years ago we were washing the fish, before going to a cruise in, and broke a rubber valve stem. Parked right at the floor jack so other jack still not needed.
I replaced all of the rubber valve stems with metal valve stems. That is one of the improvements new vehicles have that is hardly noticed.
