Outfitting questions on jack/power

[Harry Womack]

I use this jack I got from Sam's Wholesale. It rolls under the trailer and has a range from 6-1/8" to 15". It has a two stage hydraulic bottle jack. I have not seen them at Sam's for a while. The name on the jack is Shinn Fu Co. Kansas City. Model Pro Lift 4400. This jack is only about 10" long.

As you all probably know a scissors jack will slide into a space approximately 4 or so inches high and lift hgiher than a bottle jack. There are also different size scissor jacks that will slide under the same space. The only difference is the length when collapsed. Also the scissors jack is lighter than a bottle jack. My 2 cents worth.
