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

There's a little flip lever on the side of the jack mechanism- one position marked "up", the other "down". Not much to learn. A small hydraulic isn't a bad idea, it's certainly much easier and less cumbersome than trying to figure out all the folding handles/extensions on a scissors jack on the side of the road in the middle of the night. Just get a decent one- I've seen some hydraulic jacks that are flimsier and less stable than the bumper jack. Agree on the wheel chocks, too- even a couple of 2x4 cutoffs help. Plus I carry an "X" type (four way) lug wrench- that 30* factory wrench was always a pain in the @$$.
