As Ross requested here are some pics and info on my jack up legs. At full height they are 1300mm from base to top of leg. Thats not to the top of of my bracket. That gives me an extra 175mm of lift and I use every bit of it.
Leg in canopy.
This pic below shows them fully packed down. As you can see they pack down in 2 stages. Packed up they are 600mm I think with my bracket off.
This is full extention.
This one is showing how my bracket works. Ive made them so they are removable and more compact so they fit in tighter spots. They are really quick to put on or off because I only ever do the nuts up finger tight. When we went on our 3 month trip the other year I had them on the floor where the back seat is. It all fits in there and only about 80mm off the floor.
Close up of the bracket on the leg.
Cheers,
Chris.
