Levelling with Scissor Jacks

Want to see if it twists the frame? Try to open the door as you jack it up.

I did, while I had only (1)jack lifting very high. Trailer was lifted on the back left corner. Supported only by the jack, the blocking on the front left corner, and the right side wheels. I would consider a lift like that to be the 'highest' pressure possible on the frame. I was lifting from approximately 8 feet behind the axles, both doors still functioned just fine. I have a lightweight trailer with the aluminum I-beam frame, so it is 'weak' compared to a box frame trailer. I did this more for information / curiousity. I like to push things to the limit to see what happens.

Before installing the scissor jacks, I lifted a little with the stabilizer one arm jacks, held the pressure until I walked around inside the trailer... then 'snap' and one failed. So for everyone who does not believe how weak the one armed stabilizers actually are, I barely lifed with it, I would have considered in just above 'fine levelling' I hardly lifed more then I would after levelling with boards and then lowering the stabilizers and slightly lifting just to put pressure down.

The idea of the scissor jacks for me is to lift up to about 2 inches, not lift the wheels. I still carry boards for heavy levelling, then use the scissors for light levelling. I lower two stabilizers after all the levelling is done and the trailer is nearly solid.
