M105 landing gear question

[Ridgerunner]

My M105 trailer has the landing gear with the large diameter wheel. I see others have the same trailer, but have instead of the large fixed wheel, there is a two wheel telescoping jack in it's place attached to the drop down gear. How much does this type landing gear setup extend/raise?

I'm not home so I can't measure. Part of it depends on if the lunette ring is up or down. I wish the landing gear had a low range like semi trailers. It's tough to crank with a heavy load.
