Parking 5'er on sloped driveway - scissor jacks to lift?

So you are saying with the inner and outer legs of the landing gear fully extended you are not level. You must be on a very steep slope.

No need for a jack and they are not for supporting weight anyway. How would you even get it to stay in place if the slope under the pad is that steep?

Hook back up, raise the outer legs, add lumber under the landing pads and re extend the outer legs to get level.
